Given a hyperbolic surface S, a typical long geodesic arc will divide the surface into many polygons. We give statistics for the geometry of a typical tessellation. Along the way, we look at how very long geodesic arcs behave in very small balls on the surface.

It's a natural question to ask whether a morphism inducing an isomorphism on jet schemes must itself be an isomorphism. Towards this question, de Fernex, Ein, and Ishii introduced an ideal closure operation for local k-algebras (R,m,L), the ""jet closure"". The triviality of this closure operation detects a positive answer to the preceding question, and so it's natural to ask whether this closure operation is always trivial. In this talk, we give an affirmative answer to this question under mild hypothesis (i.e., when L is separable over k). Our methods are elementary, commutative-algebraic, and are inspired by similar techniques in tight closure theory.

","Workshop / Seminar","When G is a reductive (non-compact) Lie group, one can consider automorphic forms for G. These are functions on the locally symmetric space X_G associated to G that satisfy some sort of nice differential equation. When X_G has the structure of a complex manifold, the _modular forms_ for the group G are those automorphic forms that correspond to holomorphic functions on X_G. They possess close ties to arithmetic and algebraic geometry. For certain exceptional Lie groups G, the locally symmetric space X_G is not a complex manifold, yet nevertheless possesses a very special class of automorphic functions that behave similarly to the holomorphic modular forms above. Building upon work of Gan, Gross, Savin, and Wallach, I will define these modular forms and explain what is known about them.

Statistical inference provides one point of entry: unpacking the assumptions behind random graph models, we can understand what tools will help us uncover meaningful social structure from noise. The empirical design of networks problems, however, is often overlooked but fundamentally changes the space of problems available. I will discuss single-graph (N=1) problems and some of the surprising challenges behind many-graph (N >> 1) problems.

Let f : P^1 to P^n be any map. If all inflection points of the map (roots of the Wronskian of f) are all real, then the map itself can, after change of coordinates, be defined over R with real polynomials.
An equivalent statement is that certain real Schubert varieties in the Grassmannian intersect transversely -- a fact with broad combinatorial and topological consequences. The conjecture, made in the 90s, was proven by Mukhin-Tarasov-Varchenko in '05/'09 using methods from quantum mechanics.
I will present a proof of a generalization of the Shapiro-Shapiro conjecture, allowing the Wronskian to have complex conjugate pairs of roots. We decompose the real Schubert cell according to the number of such roots, and define an orientation of each connected component. For each part of this decomposition, we prove that the topological degree of the restricted Wronski map is an evaluation of a symmetric group character. In the case where all roots are real, this implies that the restricted Wronski map is a topologically trivial covering map; in particular, this gives a new proof of the Shapiro-Shapiro conjecture.

In the infinite case, one can take n = N if n is countable but in most other uncountable cases N must be much bigger than n. Stability theory is a branch of model theory studying certain definability conditions allowing us to take n = N for a large number of infinite cardinals. Historically, stability theory was first developed by Shelah for classes axiomatized by a first-order theory. In this talk, I describe a generalization to a large class of categories, accessible categories. I will also talk about recent progress on the eventual categoricity conjecture, resolved by Morley and Shelah for first-order but still open for accessible categories.

Being one of the most conserved micro-structures in nature, cilia are critical building-blocks of life. In particular, it is known for decades that our airway systems require the periodic movements of cilia to transport mucus that carries out the dusts and toxic particles. More recently, people have realized that being the ""conveyor-belt"" of unwanted particles are far from the sole function of ciliary-flows. For example, cilia can create fluid-mechanical micro environments for the active recruitment of the specific microbiome of the host; ciliary-flows in the brain ventricles behave like a ""switch"" that reliably and periodically alters the flow pattern. Despite the fact that cilia grow in greatly complex geometries, existing numerical works have focused on simple geometries and idealized boundary conditions such as periodic, free-space or half-space flows. In this talk, we will present a newly developed hybrid numerical method for simulating ciliary flows in complex geometries. The confining geometries are treated by FMM accelerated boundary integral method while the ciliary flows are treated by the method of regularized stokeslet.

This phenomenon can be measured in terms of the growth oftopological, geometric, algebraic, arithmetic and representation theoretic invariants. The Gauss-Bonnet theorem implies that the topology of a closed constant curvature surfaceis determined by the volume. In general dimension and varied curvature, a classical theoremof Gromov says that the Betti numbers are bounded by the volume. In recent years, there hasbeen a growing interest in the size of the torsion part of the homology, motivated by applicationsin number theory. Many invariants can be controlled by obtaining an efficient triangulation ora simplicial realization (or approximation). In analogy to asymptotic group theory, one line ofproblems concerns the growth of the number of manifolds of a certain type. A main tool is the emerging theory of invariant random subgroups, which is extremely efficient forthe analysis of the asymptotic behavior of certain analytic invariants as well as for some uniformresults.

Members invest in a financial market and receive an additional stream of income from passed away peers.
But, like annuities, tontines suffer from pensioners' reluctance to fund the additional stream by giving up wealth at death.
Promoting tontines, we analyze the effect of a bequest motive on the decision to invest in a tontine.
We formulate an investment problem where a pensioner chooses the percentage of wealth in the tontine, an investment strategy and their consumption rate.
The investment problem is formulated such that the optimal strategy maximizes the utility of lifetime consumption and the left behind bequest.
We show that, for a risk-averse investor, the optimal fixed percentage in the tontine is around $80\%$ for a wide range of risk aversion and different bequest motives.
We present the case of a flexible percentage together with a discussion about its suitability together with how we attempt to solve its issues. Speaker(s): Thomas Bernhardt (UM)",https://events.umich.edu/event/64725,"East Hall",1360,"East Hall",,Mathematics,"Department of Mathematics"

This much higher intensity led to new phenomena being observed, such as violet light coming out when red light went into the material. After Gérard Mourou and I developed chirped pulse amplification, also known as CPA, the intensity again increased by more than a factor of 1,000 and it once again made new types of interactions possible between light and matter. We developed a laser that could deliver short pulses of light that knocked the electrons off their atoms. This new understanding of laser-matter interactions, led to the development of new machining techniques that are used in laser eye surgery or micromachining of glass used in cell phones.

Instead of using metric for measuring distances on such manifolds, these applications often use â€œdivergence functionsâ€ for measuring proximity of two points (that do not impose symmetry and triangular inequality), for instance Kullback-Leibler divergence, Bregman divergence, f-divergence, etc. Divergence functions are tied to generalized entropy (for instance, Tsallis entropy, Renyi entropy, phi-entropy) and cross-entropy functions widely used in machine learning and information sciences. After a brief introduction to IG, I illustrate the geometry of maximum entropy inference and exponential family. I then use a general form of entropy/cross-entropy/divergence function, and show how the geometry of the underlying probability manifold (deformed exponential family) reveals an â€œescort statisticsâ€ that is hidden from the standard exponential family.

","Workshop / Seminar","Assigning characteristic classes to singular varieties is an effective way of studying the enumerative properties of the singularities. Initially one wants to consider the so-called fundamental class in H, K, or Ell, but it turns out that in Ell such a class is not well defined. However, a deformation of the notion of fundamental class (under the name of Chern-Schwartz-MacPherson class in H, motivic Chern class in K) extends to Ell, due to Borisov-Libgober. To make sense of the Borisov-Libgober class for a wider class of singularities we introduce a version of it, which now necessarily depends on new (`dynamicalâ€™ or `Kahlerâ€™) variables. We obtain that this elliptic class of Schubert varieties satisfies two different recursions (Bott-Samelson, and R-matrix recursions). The second one relates elliptic Schubert calculus with Felder-Tarasov-Varchenko weight functions, and Aganagic-Okounkov stable envelopes. The duality between the two recursions is an incarnation of 3d mirror symmetry (and symplectic duality). Joint work with A. Weber.

For a range of exponents corresponding to mild repulsion and strong attraction, we show that the minimum energy configuration of gas is uniquely attained â€” apart from translations and rotations â€” by equidistributing the particles of gas over the vertices of a regular top-dimensional simplex (i.e. an equilateral triangle in two dimensions and regular tetrahedron in three).
If the attraction is not assumed to be strong, we show these configurations are at least local energy minimizers in the relevant d-infinity metric from optimal transportation, as are all of the other uncountably many unbalanced configurations with the same support. We infer the existence of phase transitions.
An ingredient in the proof which may have independent interest is the establishment of a simple isodiametric variance bound which generalizes Popoviciuâ€™s inequality from one to higher dimensions and characterizes regular simplices: it shows that among probability measures on R^n whose supports have at most unit diameter, the variance around the mean is maximized precisely by those measures which assign mass 1/(n + 1) to each vertex of a (unit-diameter) regular simplex.

On specialization of s and t one can recover the Fibonacci numbers, the nonnegative integers, and the q-integers [n]_q. Given a quantity which is expressed in terms of products and quotients of positive integers, one obtains a Lucas analogue by replacing each factor of n in the expression with {n}. It is then natural to ask if the resulting rational function is actually a polynomial in s and t and, if so, what it counts. Using lattice paths, we give a combinatorial model for the Lucas analogue of binomial coefficients.

Our research team has expertise in cyber-security, data science and mobile security. I'll talk about my transition from academia to industry, how I found myself in cyber security, and about opportunities at Two Six. I'll talk about some of the projects I've worked on, and how my background in Mathematics intersects with my current work. We'll finish up with some fun exploits I discovered over the past year, such as causing denial of service with a PDF file, filling up the disk of a VNC server (without needing login credentials), and taking down popular websites from their user signup page.

We obtain explicit solutions or characterizations to the bookmakerâ€™s optimal bookmaking problem in various interesting models.

This talk will examine the discrete shrinking target problem for the TeichmÃ¼ller flow on the moduli space of unit-area quadratic differentials and show that for any ergodic probability measure, almost every differential will hit a nested spherical targets infinitely often provided the measures of the targets are not summable. Our key tool is an effective mean ergodic theorem stating that the time-average of any L^2 function converges to its space-average at a uniform rate in L^2. As an application, we obtain a logarithm law describing how quickly generic discrete geodesic trajectories accumulate on a given point. Joint with Grace Work.

Then I will motivate the continuous-time models making the connection between stochastic control and games with partial differential equations. I will end the talk with a presentation of asymptotic analysis of many-player games using the concept of mean-field games introduced by Pierre-Louis Lions and Jean-Michel Lasry (2006).

Machine learning has promised a new way to gain understanding and value in many industries; yet most companies are still learning how to correctly use and design ML models. The main obstacles come from many different sources, which include the inherent complexity of ML models, extracting economic value from data, deployment, integration, legacy models and innovation. At layer 6 we approach these problems from a different perspective: by engaging in research we are able to produce high impact papers as well as keep ourselves updated with the state-of-the-art approaches, by doing competitions we tune our skills into the challenges of real world data, and by working in use-cases we deal with the complexities of a large organization. In this talk I will share what is to work in this environment as well as what are the main skills that are needed to work in the ML industry.
Felipe Perez, UM Math PhD 2015, is now a Machine Learning Research Scientist at Layer 6 AI. Our Invitation to Industry Series is run in collaboration with the Erdos Institute.

","Workshop / Seminar","I will present two models of optimal consumption under a constraint that prevents the agent's consumption to fall below a certain proportion of her current ""consumption habit."" In the first model, consumption habit is the running maximum of past consumption, while the second model assumes that habit is the exponentially weighted moving average of past consumption. For each case, a stochastic control problem is formulated with the objective of maximizing the expected discounted utility of consumption stream while investing in a Black-Scholes financial market. The resulting Hamilton-Jacobi-Bellman equations are reduced to non-linear free-boundary problems that are subsequently solved semi-explicitly. The optimal consumption policy in the two models share common features in that they are mainly driven by the wealth-to-habit ratio. Furthermore, there are critical values of the wealth-to-habit ratio that determines when it is optimal to consume at the minimum acceptable rate, when should the consumption rate be above the minimum, and when is it optimal to raise the consumption habit above its current value.

The system consists of a large number of nodes in which the node dynamics depends on the joint empirical distribution of all other nodes and the corresponding edges, while the edge dynamics depends on the corresponding nodes. Asymptotic results, including law of large numbers, propagation of chaos, and central limit theorems, are established. In contrast to the classic McKean-Vlasov limit, the limiting system exhibits a path-dependent feature in that the evolution of a given particle depends on its own conditional distribution given its past trajectory. We also analyze the asymptotic behavior of the system when the edge dynamics is accelerated. A law of large number and a propagation of chaos result is established, and the limiting system is given as independent McKean-Vlasov processes. Errors between the two limiting systems, with and without acceleration in edge dynamics, are also analyzed.

When the market weights evolve via some unknown discrete time process, Fernholz proved that such portfolio maps exist, under mild and realistic assumptions. Recently, Pal and Wong showed that the problem of finding pseudo-arbitrages is equivalent to solving a certain Monge-Kantorovich optimal transport problem where the cost function is given by the so-called ""diversification return,"" which is closely related to the free energy in statistical physics. In our work, we study the regularity theory for these maps. In other words, we consider the question ""If the market conditions change slightly, does the investment portfolio also change in a continuous way?"" By addressing this problem, an unexpected connection to KÃ¤hler geometry emerges. This provides a new geometric interpretation for the regularity theory of optimal transport.

The insurer controls its surplus via reinsurance priced according to the mean-variance premium principle, as in Liang, Liang, and Young [23]. We consider the classical risk model and apply stochastic Perronâ€™s method, as introduced by Bayraktar and Sirbu [9, 10, 11], to show that the minimum discounted probability of exponential Parisian ruin is the unique viscosity solution of its Hamilton-Jacobi-Bellman equation with boundary conditions at infinity. A major difficulty in proving the comparison principle arises from the discontinuity of the Hamiltonian.

A scientific computing project requires (1) a mathematical model or set of equations describing the problem, (2) an algorithm for solving the equations, and (3) a computer program to implement the algorithm. Scientific computing research is carried out in academia, industry, and the national labs. There is continuing need to improve the accuracy and efficiency of the simulations, and to extend their scope to challenging new problems. This talk will give an overview of scientific computing and discuss some examples from my work in fluid dynamics and protein/solvent electrostatics.
