Click on title above for full website and program.

The ancient cultural interactions of Northeast Asia have left a now-imperiled record in stone across the steppes and forests of Mongolia. The historical implications of the archaeological record, and the race not only to study but to preserve this record in the face of growing threats... More >

### Combinatorics Seminar: Finite reflection groups and graph norms

Seminar | April 3 | 12:10-1 p.m. | 939 Evans Hall

David Conlon, University of Oxford

For any given graph $H$, we may define a natural corresponding functional $\|\cdot \|_H$. We then say that $H$ is norming if $\|\cdot \|_H$ is a semi-norm. A similar notion $\|\cdot \|_{r(H)}$ is defined by $\| f \|_{r(H)} := \| | f | \|_H$ and $H$ is said to be weakly norming if $\|\cdot \|_{r(H)}$ is a norm. Classical results show that weakly norming graphs are necessarily bipartite. In the... More >

### Innovations in Hiring Practices: Encouraging Social Inclusion and Diversity in the Workplace

Panel Discussion | April 3 | 12:15-1:30 p.m. | Haas School of Business, Wells Fargo Room (C420)

Liz Lowe, Innovation Lead, Sustainability and Social Impact, Adobe; Virginia Martinez-Martin, Recruiting Lead, IDEO; Devan Vaughn, Program Manager, Global Talent Acquisition, Microsoft

Don Moore, Lorraine Tyson Mitchell Chair in Leadership and Communication, Berkeley-Haas School of Business

Center for Responsible Business

Join us for a lunch-time panel which will discuss better alternatives to traditional hiring practices to create work forces that are not only productive but also socially inclusive and diverse.

Companies sometimes do a poor job of predicting future job performance and often discriminate against underrepresented minorities. How can companies avoid these pitfalls and implement better hiring... More >

### Differential Geometry Seminar: Appearance of stable spheres along the Ricci flow in positive scalar curvature

Seminar | April 3 | 1:10-2 p.m. | 939 Evans Hall

Antoine Song, Princeton

For a 3-manifold M not isometric to the round sphere, with scalar curvature at least 6 and positive Ricci curvature, Marques and Neves proved a 3-dimensional version of the Toponogov theorem: there exists an embedded minimal surface S of area less than $4\pi $. Their proof uses a combination of min-max theory for minimal surfaces and the Ricci flow. While the general case (no assumption on the... More >

### Seminar 211, Economic History: "Bombs, Broadcasts and Betrayal at the Home Front: Determinants of Treason in Germany During World War II"

Seminar | April 3 | 2-3:30 p.m. | 639 Evans Hall

Maria Petrova, Barcelona Graduate School of Economics

### String-Math Seminar: A new look at quantum knot invariants

Seminar | April 3 | 2-3 p.m. | 402 LeConte Hall | Canceled

Aaron Lauda, UCS

The Reshetikhin-Turaev construction associated knot invariants to the data of a simple Lie algebra and a choice of irreducible representation. The Jones polynomial is the most famous example coming from the Lie algebra sl(2) and its two-dimensional representation. In this talk we will explain Cautis-Kamnitzer-Morrison's novel new approach to studying RT invariants associated to the Lie algebra... More >

### Northern California Symplectic Geometry Seminar: Orientations of moduli spaces for Legendrian contact homology/Real Gromov-Witten theory in all genera

Seminar | April 3 | 2:30-5:10 p.m. | 939 Evans Hall

Cecilia Karlsson/Penka Georgieva, Stanford/Pierre et Marie Curie

2:30 PM Karlsson) : I will give an introduction to Legendrian contact homology, which is an invariant of Legendrian submanifolds that is defined by using pseudo-holomorphic disk techniques. In particular, I will explain how one can define this homology with integer coefficients by orienting the moduli space of the pseudo-holomorphic disks. I will also discuss how one can make this invariant... More >

### Probabilistic Operator Algebra Seminar: Spectral theory of normal unbounded operators and applications

Seminar | April 3 | 3-5 p.m. | Evans Hall, 736 Evans

Brent Nelson, NSF Postdoctoral Fellow UC Berkeley

In this introductory talk we start by recapitulating basic properties of unbounded operators. Proceeding with the functional calculus for normal operators, we then discuss applications thereof such as Stone's theorem and operators affiliated to von Neumann algebras.

### Analysis and PDE Seminar: Models for Rayleigh-Taylor mixing and interface turnover

Seminar | April 3 | 4:10-5 p.m. | 740 Evans Hall

Steve Shkoller, UC Davis

The instability of a heavy fluid layer supported by a light one is generally known as Rayleigh-Taylor (RT) instability. It can occur under gravity and, equivalently, under an acceleration of the fluid system in the direction toward the denser fluid. Whenever the pressure is higher in the lighter fluid, the differential acceleration causes the two fluids to mix.

The Euler equations serve as the... More >
