### Matrix Computations and Scientific Computing Seminar: Sketched Ridge Regression

Seminar | January 25 | 11:10 a.m.-12 p.m. | 380 Soda Hall

Shusen Wang, UC Berkeley

Previous work has applied matrix sketching to speed up the least squares regression (LSR) on the n >> d data. Theoretical analysis of the sketched LSR is has been well established and refined. How the results extend to the sketched ridge regression is yet unclear. In our recent work, we study two types of the sketched ridge regression—the classical sketch and the Hessian sketch--- from two... More >

### The effects of intranasal oxytocin on mentalization in individuals with and without schizophrenia

Colloquium | January 25 | 12:10-1:15 p.m. | 5101 Tolman Hall

Joshua Woolley, Assistant Professor, UC San Francisco

Institute of Personality and Social Research

There is growing interest in the use of intranasal oxytocin administration to alter social behavior and functioning in healthy and patient populations. In particular, there is growing excitement that oxytocin may be a novel approach for treatment of social cognitive deficits in schizophrenia, which are important causes of worse clinical, functional, and occupational outcomes. However, there is... More >

### Topology Seminar (Introductory Talk): Dunfield and Thurston’s stable description of certain finite $\text{Mod}(\Sigma_g)$ actions

Seminar | January 25 | 2:10-3 p.m. | 736 Evans Hall

Eric Samperton, UC Davis

Let $X_g : = \{ \pi _1(\Sigma _g) \to G\}$. The mapping class group $\text {Mod}(\Sigma _g)$ acts on $X_g/Aut(G)$. Using the classification of finite simple groups, Dunfield and Thurston gave a complete description of this action when $G$ is nonabelian simple, and $g$ is large enough. I will review their theorem.

### Self-avoiding walks on graphs and groups

Seminar | January 25 | 3:10-4 p.m. | 1011 Evans Hall

Geoffrey Grimmett, Cambridge University

The problem of self-avoiding walks (SAWs) arose in statistical mechanics in the 1940s, and has connections to probability, combinatorics, and the geometry of groups. The basic question is to count SAWs. The so-called 'connective constant' is the exponential growth rate of the number of n-step SAWs. We summarise joint work with Zhongyang Li concerned with the question of how the connective... More >

This talk focus on the Distributed-memory hierarchical interpolative factorization (DHIF) which offers an efficient way for solving or preconditioning elliptic partial differential equations. By exploiting locality and low-rank properties of the operators, the DHIF achieves quasi-linear complexity for factorizing the discrete positive definite elliptic operator and linear complexity for solving...

David Zureick-Brown, Emory University

Let X be a curve of genus g over a number field F of degree d = [F:Q]. The conjectural existence of a uniform bound N(g,d) on the number #X(F) of F-rational points of X is an outstanding open problem in arithmetic geometry, known to follow from the Bomberi-Lang conjecture. ... More >

### A Bayesian Multivariate Functional Dynamic Linear Model

Seminar | January 25 | 4-5 p.m. | 1011 Evans Hall

Daniel Kowal, Cornell University

I will present a Bayesian approach for modeling multivariate, dependent functional data. To account for the three dominant structural features in the data--functional, time dependent, and multivariate components--we extend hierarchical dynamic linear models for multivariate time series to the functional data setting. We also develop Bayesian spline theory in a more general constrained... More >

### Topology Seminar (Main Talk): Computational complexity and 3-manifolds and zombies

Seminar | January 25 | 4:10-5 p.m. | 3 Evans Hall

Eric Samperton, UC Davis

We consider the computational complexity of counting homomorphisms from 3-manifold groups to fixed finite groups $G$. Let $G$ either be non-abelian simple or $S_m$, where $m \geq 5$. Then counting homomorphisms from fundamental groups of 3-manifolds to $G$ is $\mathsf { P}$-complete. In particular, for fixed $m \geq 5$, it is $\mathsf {NP}$-complete to decide when a 3-manifold admits a connected... More >

### Combinatorics Seminar: Pseudorandomness in graph theory and additive combinatorics

Seminar | January 25 | 4:10-5 p.m. | 740 Evans Hall

Yufei Zhao, University of Oxford

(Please note the unusual time and place of this talk.)

I will highlight some connections between graph theory and additive combinatorics. I will explain how to prove the celebrated Green-Tao theorem, that the primes contain arbitrarily long arithmetic progressions. Following a graph theoretic viewpoint, we will see an answer to the question: what kinds of pseudorandomness are used in the proof... More >
