CMSA Colloquium: An exploration of infinite games—infinite Wordle and the Mastermind numbers
October 16, 2023 4:30 pmSpeaker: Joel D. Hamkins
Let us explore the nature of strategic reasoning in infinite games, focusing on the cases of infinite Wordle and infinite Mastermind. The familiar game of Wordle extends naturally to longer...

CMSA Topological Quantum Matter Seminar: Breaking ergodicity: quantum scars and regular eigenstates
October 16, 2023 2:00 pmSpeaker: Ceren Dag
Quantum many-body scars (QMBS) consist of a few low-entropy eigenstates in an otherwise chaotic many-body spectrum and can weakly break ergodicity resulting in robust oscillatory dynamics. The notion of QMBS...

Algebraic Geometry in String Theory Seminar: Moduli of boundary polarized Calabi-Yau pairs
October 16, 2023 10:00 amSpeaker: Dori Bejleri
The theories of KSBA stability and K-stability furnish compact moduli spaces of general type pairs and Fano pairs respectively. However, much less is known about the moduli theory of Calabi-Yau...

Gauge Theory and Topology Seminar: On Freedman’s Link Packings
October 13, 2023 3:30 pmSpeaker: Elia Portnoy
Freedman recently posed a new question in quantitative topology about link packings. Given a link L, define the $\epsilon$-diagonal packing number $n_{L(\epsilon)}$ to be the number of copies of L...

Richard P. Stanley Seminar in Combinatorics: Improved bounds for Heilbronn’s triangle problem and connections to projection theory
October 13, 2023 3:00 pmSpeaker: Alex Cohen and Dmitrii Zakharov
Heilbronn’s triangle problem asks, how small is the smallest triangle formed by a set of points? Suppose n points are placed in the unit square and Delta is the smallest...

CMSA Active Matter Seminar: Contractility, structure formation and fluctuations in active gels, with and without molecular motors
October 12, 2023 1:00 pmSpeaker: Fred MacKintosh
Various processes in living cells depend on contractile forces that are often generated by myosin motors in concert with polar actin filaments. A textbook example of this is the actomyosin...

CMSA Quantum Matter in Mathematics and Physics: Non-invertible symmetries, leptons, quarks, and why multiple generations
October 11, 2023 4:30 pmSpeaker: Seth Koren
Generalized global symmetries are present in theories of particle physics, and understanding their structure can give insight into these theories and UV completions thereof. After discussing the generalized symmetries of the...
