SUMMARY:Workshop / Seminar:Student Commutative Algebra: Binomial rings and λ-rings
DESCRIPTION:A commutative ring is said to be binomial if it is torsion-free as a 𝐙-module and contains all binomial coefficients. A λ-ring is a commutative ring with additional structure\, modelling after exterior powers of vector spaces. In this talk\, we will see some examples of properties of these types of rings\, as well as the relation between the two definitions.

SUMMARY:Lecture / Discussion:2025 Van Eenam Lectures
DESCRIPTION:Lectures each day November 18-20\, 2025 from 4-5 pm in East Hall. \n\n*Lecture 1\, November 18\, 4 pm\, East Hall 1360: E-values and e-processes: Theory and applications*\nE-values and e-processes are potential alternatives to p-values as measures of uncertainty\, significance and evidence. We first briefly introduce the theory of e-values and e-processes\, and then briefly discuss their applications in four areas: a) Combining dependent p-values\; b) Selective inference procedures\; c) Backtesting risk measures\; d) Online large language models (LLM) watermark detection. \n\n*Lecture 2\, November 19\, 4 pm East Hall 1360: Risk aversion\, insurance propensity\, and choice under dependence*\nWe provide a foundation of risk aversion by showing that this attitude is fully captured by the propensity to seize insurance opportunities. Our foundation well accords with the commonly held prudential interpretation of risk aversion that dates back to the seminal works of Arrow (1963) and Pratt (1964). These analyses are special cases of results in the general framework of choice under dependence.\n\n*Lecture 3\, November 20\, 4 pm East Hall 4448: Bridging pure risk and ambiguity in risk measures and optimization*\nWe discuss optimization and modeling of ambiguity in risk management and decision making. We first discuss two different approaches in optimization under uncertainty\, the worst-case risk approach and the model aggregation approach. Then we present a mathematical framework using a sigma-algebra to distinguish between pure risks and ambiguity.\n\nDr. Ruodu Wang is Tier-1 Canada Research Chair in Quantitative Risk Management and Professor of Actuarial Science and Quantitative Finance at the University of Waterloo. He received his PhD in Mathematics (2012) from the Georgia Institute of Technology\, after completing his Bachelor (2006) and Master’s (2009) degrees at Peking University. He holds editorial positions in 8 leading journals in actuarial science\, operations research\, statistics\, and economics\, including Co-Editor of ASTIN Bulletin - The Journal of the International Actuarial Association and Co-Editor of the European Actuarial Journal. Among other international awards and recognitions\, he is the first winner of the SOA Actuarial Science Early Career Award (2021) from the Society of Actuaries\, and a Fellow of the Institute of Mathematical Statistics (elected 2022). His research papers are published in top journals across a wide range of scientific fields\, such as the American Economic Review\, the Annals of Statistics\, the Journal of the Royal Statistical Society (Series B)\, Management Science\, Operations Research\, and the Proceedings of the National Academy of Sciences.\n\nVan Eenam Lectures: This lecture series is funded by the Weltha McLachlan Van Eenam\, Marjorie Van Eenam Butcher and Robert Ward Butcher Actuarial/Financial Mathematics Fund.\n\nThe Fund was established in memory of the Esteemed Emeritus Professor Cecil J. Nesbitt who was a dear friend of Marjorie Van Eenam Butcher (pictured) and Robert Ward Butcher. The fund was created as part of the Weltha McLachlan Van Eenam Memorial Fund to benefit Actuarial/Financial Mathematics in the Department of Mathematics at the University of Michigan.

SUMMARY:Workshop / Seminar:An Introduction to Operads
DESCRIPTION:An operad O can be thought of as a sequence of spaces O(n) which encode “n-ary operations” satisfying certain compatibility axioms for compositions\, units\, and actions by the symmetric group. Different operads encode different properties that n-ary operations might possess: for instance\, the “commutative operad” Comm encodes what it means for an n-ary operation to be (“on the nose”) commutative\, while the associative operad Assoc encodes (“on the nose”) associativity. Motivated by the homotopy-associative property of loop concatenation in loop spaces\, we’ll introduce A_infinity operads and algebras over them. We’ll finish the talk with the little n-cubes operad and algebras over them (E_n / E_infinity spaces)\, which possess a “higher homotopy” analogue of commutativity.

SUMMARY:Workshop / Seminar:CM-AMO Seminar | Tests of fundamental physics with thorium nuclear clocks
DESCRIPTION:Clocks based on hyperfine and electronic transitions in laser-cooled atoms\, with fractional inaccuracy and instability now reaching below 1e-18\, have revolutionized positioning\, navigation\, and timekeeping (PNT) and serve as one of the experimental foundations on which the Standard Model of particle physics is built.  A new type of clock based on the internal transitions of atomic nuclei\, dubbed nuclear clocks\, was proposed by Peik and Tamm in 2003.  Among nuclei\, the thorium-229 nucleus is unique in having a transition at low enough energy to be accessible with present-day laser technology\, and laser spectroscopy of the 148 nm thorium-229 nuclear isomer transition was first demonstrated by three groups nearly simultaneously in 2024.  Due to the higher energy scales and additional fundamental interactions present in the nucleus\, nuclear transitions are much more sensitive to small deviations from the predictions of the Standard Model than atomic transitions.  Thus\, thorium nuclear clocks may offer insights about unification theories\, the nature of dark matter\, or other physics beyond the Standard Model.\n\nI will begin this talk with a brief overview of the thorium-229 nuclear isomer transition and the two experimental approaches currently being pursued to build thorium nuclear clocks: one based on thorium doped into solid-state hosts and the other based on trapped and laser-cooled thorium ions.  Next\, I will present the design and current status of a trapped-ion thorium clock experiment under construction in my lab at UCLA.  Finally\, I will conclude with a discussion of the fundamental physics reach of this and other thorium nuclear clocks.\n\nBio: David Leibrandt is a Professor in the Department of Physics & Astronomy at UCLA. Prior to moving to UCLA in 2022\, he led the trapped-ion optical atomic clock and precision measurement experiments within the Ion Storage Group at the National Institute of Standards and Technology in Boulder\, CO. He received his Ph.D. in Physics from the Massachusetts Institute of Technology (MIT) in 2009 and his B.S.E. in Engineering Physics from the University of Michigan in 2004. David is a Fellow of the American Physical Society and a recipient of the EFTF Young Scientist Award and the Department of Commerce Gold Medal Award for the development of optical atomic clocks based on quantum-logic spectroscopy of aluminum ions with record fractional inaccuracy below 1e-18.
