Mathematical Conversations

Symmetries in symbolic dynamics
Bryna Kra
5:30pm|Remote Access

Originating in the work of Hadamard in the 1890’s on the coding of geodesic flow, symbolic dynamics has become a key tool for studying topological, smooth, and measurable dynamical systems. The automorphism group of a symbolic system capture its...

Geometric and Modular Representation Theory Seminar

Frobenius exact symmetric tensor categories
3:00pm|Simonyi Hall 101 and Remote Access

I will report on a joint work in progress with K. Coulembier and V. Ostrik. We show that a symmetric tensor category in characteristic $p > 0$ admits a fiber functor to the Verlinde category (semisimplification of $Rep(Z/p)$) if and only if it has...

Interview with Dr. Monica Vazirani
Monica Vazirani
1:00pm

Dr. Monica Vazirani is a professor at UC Davis.  She received her PhD from UC Berkeley in 1999, after which she had an NSF postdoc she spent at UC San Diego and UC Berkeley, as well as postdoctoral positions at MSRI and Caltech.  Dr. Vazirani's...

SL2 Seminar

Automorphic gluing functor in Betti geometric Langlands
4:00pm|Remote Access

I'll discuss joint work with Zhiwei Yun constructing a natural functor from the automorphic category of a nodal curve to the automorphic category of a smoothing. The results depend on the microlocal geometry of sheaves with nilpotent singular...

Computer Science/Discrete Mathematics Seminar I

A Complexity-Theoretic Perspective on Fairness
Michael P. Kim
11:15am|Simonyi Hall 101 and Remote Access - see Zoom link below

Algorithms make predictions about people constantly.  The spread of such prediction systems has raised concerns that algorithms may exhibit unfair discrimination, especially against individuals from minority groups.  While it's easy to speculate on...

Joint IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar

Unexpected fillings, singularities, and plane curve arrangements
Laura Starkston
9:15am|Remote Access

I will discuss joint work with Olga Plamenevskaya studying symplectic fillings of links of certain complex surface singularities, and comparing symplectic fillings with complex smoothings. We develop characterizations of the symplectic fillings...

Joint IAS/Princeton University Number Theory Seminar

Groups with bounded generation: old and new
4:30pm|Remote Access
A group is said to have bounded generation (BG) if it is a finite product of cyclic subgroups. We will survey the known examples of groups with (BG) and their properties. We will then report on a recent result (joint with P. Corvaja, J. Ren and U...
