### Probabilistic Operator Algebra Seminar: Free Stein discrepancy as a regularity condition

Seminar | August 21 | 3-5 p.m. | 736 Evans Hall

Brent Nelson, NSF Postdoctoral Fellow UC Berkeley

Given an n-tuple of non-commutative random variables, its free Stein discrepancy relative to the semicircle law measures how close the distribution is to the semicircle law. By considering free Stein discrepancies relative to a broader class of laws, one can define a quantity called the free Stein information. In this talk, we will discuss this and its relation to other free probabilistic... More >

Colloquium | August 23 | 12:10-1:15 p.m. | 5101 Tolman Hall

Andrew Fox, Assistant Professor, UC Davis

An extremely anxious temperament early in life is a risk factor for the later development of anxiety, depressive, and substance abuse disorders. Children with an extremely anxious temperament (AT), react to novelty with increased behavioral inhibition and increased levels of physiological arousal. Using a well-validated non-human primate model of AT, our group has been investigating the... More >

On a locally finite graph, consider the following interacting particle system, known as Activated Random Walk (ARW).

Sleepy particles become active on coming in contact with active particles... More >

### Berkeley-Tokyo Summer School "Geometry, Representation Theory, and Mathematical Physics": Fukaya cosheaves

Seminar | August 23 | 3:30-5 p.m. | 375 LeConte Hall

Kontsevich conjectured that the wrapped Fukaya category of a Weinstein manifold should be computable as the global sections of some cosheaf of categories over its Lagrangian skeleton. I will describe how to make this precise, and how to prove it. This is joint work with Sheel Ganatra and John Pardon.

### Nonparametric network comparison

Seminar | August 24 | 4-5 p.m. | 332 Evans Hall

Patrick Wolfe, Purdue University

Understanding how two networks differ, or quantifying the degree to which a single network departs from a given model, is a challenging question in modern mathematical statistics. Here we show how subgraph densities, which for large graphs play a role analogous to moments in the context of random variables, enable a natural means of nonparametric network comparison. Coupled with a partial order... More >

Seminar | August 25 | 1:15-2:45 p.m. | 375 LeConte Hall

Andrea D'Agnolo, University of Padova

The classical Riemann-Hilbert correspondence establishes an equivalence between the triangulated categories of regular holonomic D-modules and of constructible sheaves. In a joint work with Masaki Kashiwara, we proved a Riemann-Hilbert correspondence for holonomic D-modules which are not necessarily regular. The construction of our target category is based on the theory of ind-sheaves by... More >

### Logic Colloquium: A constructive solution to Tarski's circle squaring problem

Colloquium | August 25 | 4-5 p.m. | 60 Evans Hall

Andrew Marks, U.C. Los Angeles

In 1925, Tarski posed the problem of whether a disc in $R^2$ can be partitioned into finitely many pieces which can be rearranged by isometries to form a square of the same area. Unlike the Banach-Tarski paradox in $R^3$, it can be shown that two Lebesgue measurable sets in $R^2$ cannot be equidecomposed by isometries unless they have the same measure. Hence, the disk and square must necessarily... More >
