SUMMARY:Workshop / Seminar:Stability\, Approximation\, and Robustness of Optimal Policies in POMDPs
DESCRIPTION:In this talk\, I will focus on the stability\, approximation\, and robustness of optimal policies in partially observable Markov decision processes (POMDPs) under discounted and average cost criteria.\n\nI will begin with filter kernel perturbation under model change. I will establish how small perturbations in the transition or observation kernels lead to explicit\, nonasymptotic bounds on both the filter kernel and the performance of the induced policies. A primary result demonstrates that an optimal policy computed under an incorrect model remains near optimal for the true model\, with quantitatively bounded errors.\n\nBuilding on these stability concepts\, I will then talk about the average cost setting and describe conditions under which the nonlinear filter exhibits a contraction property. Under these conditions\, the vanishing discounted approach yields a solution to the average cost optimality equation\, guaranteeing the existence of a stationary optimal policy. Furthermore\, this provides explicit bounds that quantify the influence of initial prior distribution errors and model errors on long run performance.\n\nFinally\, I will present results on implementable approximations. I will introduce refined error bounds for finite window controllers and conclude by discussing how Q learning can be utilized through either finite window or the quantization of the belief process to obtain near optimal policies for both discounted and average cost criteria.

SUMMARY:Workshop / Seminar:DE Seminar: Mathematical Analysis of Many-Body Quantum Simulation with Coulomb Potentials
DESCRIPTION:Efficient simulation of many-body quantum dynamics is central to advances in physics\, chemistry\, and quantum computing. A fundamental question is whether the simulation cost can scale polynomially with system size in the presence of realistic interactions. In this talk\, we focus on many-body quantum systems with Coulomb interactions\, which play a central role in electronic and molecular dynamics. We prove that first-order Trotterization for such unbounded Hamiltonians admits a polynomial dependence on the number of particles in the continuum limit\, with a convergence rate of order $1/4$—in contrast to prior Trotter analyses for bounded operators\, which diverge in this limit. The result holds for all initial wavefunctions in the domain of the Hamiltonian. This $1/4$-order rate is optimal\, as previous work shows that it can be saturated by the ground state of the hydrogen atom. Moreover\, higher-order Trotter formulas do not improve the worst-case scaling. We also discuss additional regularity conditions on the initial state under which the original Trotter convergence rate can be recovered. Finally\, we discuss our recent development on the spatial error and algorithm complexities.

SUMMARY:Lecture / Discussion:Pseudo-magnetism in a strained discrete honeycomb lattice
DESCRIPTION:Abstract: Slowly-varying nonuniform strain in honeycomb media can generate an effective pseudo-magnetic field\, even though the underlying medium is non-magnetic. This phenomenon was first discovered in graphene and later in photonic crystals\, and other physical settings. In this talk\, I will start from a discrete nearest-neighbor tight-binding model for a nonuniformly strained honeycomb medium. I will then show how this model leads to a continuum magnetic Dirac Hamiltonian that describes wave packets concentrated near a Dirac point of the undeformed structure. I will focus on unidirectional deformations with bounded gradients that preserve translation invariance along the armchair direction. In this setting\, we prove the existence of eigenmodes that behave like plane waves along the armchair direction and are strongly localized in the transverse direction\, together with quantitative correction estimates. These results apply to deformations that produce an approximately constant pseudo-magnetic field perpendicular to the plane. They also lead to nearly flat bands and\, as a consequence\, a very high density of states. These analytical results are also supported by numerical simulations of the corresponding deformations. This is joint work with Michael I. Weinstein.\n\nContact:  Ian Tobasco

SUMMARY:Workshop / Seminar:Optimal Contract\, Delegated Investment\, and Information Acquisition
DESCRIPTION:We study a model of delegated investment within a noisy rational expectations equilibrium framework. Portfolio managers can acquire costly private information about asset payoffs but incur portfolio management costs\, and are compensated by investors to make investment decisions on their behalf. We show that the optimal contract features a benchmark component that mitigates the agency frictions arising from portfolio management costs. The precision of managers' private information is determined endogenously in market equilibrium\, with private and public information acting as substitutes. As portfolio management costs increase\, both the performance-based and benchmark components of the optimal contract become more sensitive to investment outcomes\, while fewer private signals are incorporated into prices\, reducing market informational efficiency. We further show that when a social planner places sufficient weight on the welfare of direct investors and liquidity providers\, the socially optimal equilibrium achieves greater price informational efficiency than the decentralized equilibrium. The talk will focus on the interaction between optimal contracting\, information acquisition\, and market efficiency\, together with the economic intuition underlying these results.

SUMMARY:Lecture / Discussion:Foundation models and agentic AI for discovery in fluid mechanics
DESCRIPTION:Abstract:  In this seminar we discuss a unified framework that combines explainable deep learning\, deep reinforcement learning (DRL) and foundation models to advance both understanding and control of turbulence\, with direct implications for accelerated design and discovery. First\, we will show how explainable deep learning techniques can be used to identify the flow features that are truly responsible for key turbulent processes in wall-bounded flows. By systematically interrogating trained neural networks\, we uncover the most influential coherent structures driving momentum transport and drag. Our results reveal that classically studied structures (while important) provide only a partial and sometimes misleading perspective\, motivating a more data-driven and physics-aware view of turbulence organization. Building on these insights\, we will demonstrate how deep reinforcement learning can be used to actively control turbulent flows by targeting the dynamically relevant structures identified through explainability. This approach achieves over 30% drag reduction in canonical wall-bounded turbulence and extends naturally to more complex configurations\, including turbulent wings\, highlighting the scalability of learning-based control strategies. Finally\, we will introduce a foundation-model-based framework for accelerated design\, optimization and scientific discovery. By learning compact\, interpretable latent representations of high-dimensional flow physics\, these models (combined with agentic-AI systems) enable rapid exploration of design spaces\, causal reasoning and closed-loop optimization\, bridging the gap between expensive simulations\, control and engineering decision making. Together\, these results illustrate how explainable and agentic AI are becoming essential for turbulence physics\, flow control and next-generation engineering design.\n\n\nContact:  Silas Alben

SUMMARY:Workshop / Seminar:Buying Time: Optimal Service Purchase and Retirement Timing in Defined Benefit Plans
DESCRIPTION:We study retirement timing decisions in a defined benefit (DB) pension plan with a service-purchase\noption. An employee who would otherwise retire at a fixed time T may elect to purchase L additional\nyears of service and retire early. Earlier retirement provides additional leisure but requires an upfront\npayment and typically results in a reduced post-retirement income stream. We model this trade-off in\na continuous-time retirement framework by allowing the employee to choose L to maximize the value\nof wealth and leisure at retirement in both deterministic and life-contingent settings. Our model\ncaptures a common feature of public pension systems: early retirement is often accompanied by both\nan upfront cost and a permanent reduction in benefits. We show that this structure yields tractable\nand intuitive results in several benchmark cases\, including settings without mortality risk and settings\nwith mortality risk under simplifying assumptions. In more general cases\, we characterize optimal\nbehavior through comparative statics and numerical examples. A key insight is that the interaction\nbetween the finite-horizon value of leisure and the lifetime cost embedded in pension pricing can\ngenerate a range of behaviors\, including monotone strategies and interior optima. While many results\nalign with economic intuition\, others require more careful interpretation. We also extend the model to\nallow for dynamic decision-making via a multi-period service-purchase option\, solved by backward\ninduction. The results provide insight into optimal retirement timing and the role of plan design in\nshaping participant behavior. This is joint work with David Kausch and Virginia Young.

SUMMARY:Workshop / Seminar:Quantitative propagation of chaos and universality for asymmetric Langevin spin glass dynamics
DESCRIPTION:We obtain quantitative estimates on quenched propagation of chaos for Langevin spin glass dynamics with i.i.d. disorder. Prior work in the case of Gaussian disorder established the qualitative convergence of the law of a single spin to a deterministic McKean--Vlasov limit. We prove convergence rates in expected Wasserstein distance and quantitative concentration rates for Lipschitz observables under the assumption that the disorder satisfies the T_2 inequality. The proof uses a coupling argument\, together with techniques from concentration of measure\, filtering theory\, and Malliavin calculus.

SUMMARY:Workshop / Seminar:Robust and Risk-Sensitive Acceleration in Gradient Methods
DESCRIPTION:First-order methods such as gradient descent (GD) are foundational in optimization. In unconstrained problems with exact gradients\, momentum-based methods—most notably Nesterov’s accelerated gradient descent (AGD) and Polyak’s heavy-ball (HB) method—achieve faster convergence by improving dependence on the condition number. However\, this acceleration comes at a cost: momentum amplifies gradient noise\, making these methods less robust than GD under standard parameter choices and requiring more accurate gradient estimates to attain comparable accuracy. Similar challenges arise in convex and nonconvex min–max optimization.\nMotivated by applications in machine learning\, this talk studies unconstrained and min–max optimization under deterministic\, unbiased stochastic\, and biased stochastic gradient noise. I will present new algorithms that achieve optimal robustness against different noise types\, using control-theoretic tools such as the H_2​ norm\, the H_∞​ norm\, and the risk-sensitivity index\, together with coherent risk measures. I will also discuss worst-case noise constructions and high-probability convergence guarantees. This perspective builds a bridge between optimization and robust control theory and enables the design of noise-robust and risk-sensitive accelerated methods.\nRepresentative Publications:\nM.

SUMMARY:Workshop / Seminar:Kullback–Leibler Mirror-Prox for Measure-Valued Variational Inequalities and Mean-Field Equilibria
DESCRIPTION:We study the computation of static mean-field equilibria on a compact state space by formu-\nlating the equilibrium condition as a variational inequality over probability measures. We propose\nan entropic variant of Korpelevich’s extragradient algorithm—the Kullback–Leibler Mirror-Prox\nmethod—in which Euclidean projections are replaced by relative-entropy proximal steps. Each\nhalf-step is therefore an explicit exponential reweighting of the current measure\, implemented on a\nfinite state-space discretization. Under Lasry–Lions monotonicity and continuity assumptions\, we\nprove convergence of mesh-refined ergodic averages and obtain finite-iteration Minty-residual and\napproximate-equilibrium bounds that jointly quantify iteration and discretization errors. Under\nstrong monotonicity\, we derive metric convergence rates for the last\, best\, and averaged iterates.\nWe also develop a KL-type Tikhonov regularization that selects the equilibrium minimizing relative\nentropy with respect to a reference measure. The framework applies to potential and nonpotential\ncost operators and does not require differentiability or convexity of the cost in the individual state.\n\nJoint work with Erhan Bayraktar\, Ibrahim Ekren and Lu Vy.

SUMMARY:Workshop / Seminar:Exploratory Optimal Reinsurance under the Mean-Variance Criterion
DESCRIPTION:This paper proposes a Reinforcement Learning (RL) approach to the optimal reinsurance problem\nwhen the insurer faces uncertainty about the insurance claim dynamics. To this end\, we first formulate\nan exploratory version of the problem as a relaxed stochastic control problem. Within a broad class of\nparametric retention functions and general risk loading functions\, we derive the closed-form equilibrium\npolicy under the continuous-time mean-variance criterion. This is achieved through a formal verification\ntheorem and solving classical solutions of a system of exploratory extended Hamilton-Jacobi-Bellman\n(EEHJB) equations. We then establish a policy iteration theorem\, showing that starting from any timeand state-homogeneous policy\, policy iteration converges to the derived equilibrium policy. Next\, we\ndevelop a martingale orthogonality theorem\, which serves as the foundation of our RL algorithm. The\nalgorithm is evaluated through simulation studies and real data from the U.S. National Flood Insurance\nProgram. Results demonstrate that the RL approach effectively learns unknown claim distributions\,\ntracks unobserved changes in claim dynamics and produces higher insurer surplus trajectories than the\nmaximum likelihood estimation (MLE) approach while simultaneously exhibiting greater robustness to\nthe choice of training window.

SUMMARY:Workshop / Seminar:A New Approach for the Continuous Time Kyle-Back Strategic Insider Equilibrium Problem
DESCRIPTION:In this talk\, we consider a continuous-time Kyle-Back model which is a game between an insider and a market maker. The existing literature typically focuses on constructing equilibria with a PDE approach\, which requires certain Markovian structures. We characterize all equilibria through a coupled system of forward-backward SDEs. In particular\, when the time duration is small\, we show that the FBSDE is well-posed\, and therefore the game has a unique equilibrium. Moreover\, this unique equilibrium may be non-Markovian and thus not attainable via the PDE approach. We next study the set value of the game\, which roughly speaking is the set of insider's values over all equilibria and thus is by nature unique. Finally\, we characterize the set value through a level set of a certain standard HJB equation.\nIn the second part of the talk\, we apply the new approach to the Kyle-Back model with dynamic legal risk and large numbers of noise traders. In this setting\, the insider chooses a strategy that conceals his identity within a large volume of surrounding trades and concentrates on medium-sized trades.  We establish an intensity-based mathematical framework for explaining the interconnections between insider trading and stealth trading. When the number of noise traders becomes large\, the price impact of the insider asymptotically vanishes\, and consequently the stochastic game becomes deterministic optimizations\, which also carry implications for regulatory investigations and sanctions.\n\nThe results above include the joint work with Weixuan Xia and with Jianfeng Zhang.

SUMMARY:Workshop / Seminar:THE HEREDITARY LAWS OF LARGE NUMBERS
DESCRIPTION:The celebrated theorem of Komlos (1967) establishes L^1-boundedness as a sufficient condition for a sequence of measurable functions on a probability space to contain a subsequence along which\, and along whose every further subsequence (“hereditarily”)\, the Cesaro averages converge to a “randomized mean” in the spirit of the Strong law of Large Numbers. We provide conditions not only sufficient\, but also necessary\, for this result\, as well as for the hereditary analogues of the Weak Law of Large Numbers\, of the Hsu-Robbins-Erdos Law of Large Numbers\, and of the Law of the Iterated Logarithm. \n\nJoint work with I. Berkes (Budapest) and W. Schachermayer (Vienna).

SUMMARY:Workshop / Seminar:The optimal rate of convergence in mean field control
DESCRIPTION:I will discuss the sharp rate of convergence of the value functions of N-particle stochastic control problems to their mean field limit\, for merely Lipschitz mean field costs. For d ≥ 2\, the optimal rate is that of the empirical measures of i.i.d. samples in the 1-Wasserstein distance\, as conjectured by Daudin\, Delarue\, and Jackson\, and it persists with additive common noise. In dimension one\, this benchmark can surprisingly be beaten: cooperating particles outperform independent samples\, and the optimal exponent is 4/7\, strictly between the accuracy of independent sampling (N^{-1/2}) and that of quantization (N^{-1}). The proofs rely on a new control-theoretic technique of recoupled shadow flows and\, in dimension one\, on a Gibbs law implementing the cooperation and a Schrödinger ground-state estimate.
