Paris/Berkeley/Bonn/Zürich Analysis Seminar: Lower bounds on eigenfunctions on hyperbolic surfaces

Seminar | January 25 | 9:10-10 a.m. | 238 Sutardja Dai Hall

 Semyon Dyatlov, UC Berkeley and MIT

 Department of Mathematics

I show that on a compact hyperbolic surface, the mass of an $L^2$-normalized eigenfunction of the Laplacian on any nonempty open set is bounded below by a positive constant depending on the set, but not on the eigenvalue. This statement, more precisely its stronger semiclassical version, has many applications including control for the Schrödinger equation and the full support property for...   More >

Curators’ Talk: Lawrence Rinder and Julia White on To the Letter

Panel Discussion | January 25 | 12 p.m. |  Berkeley Art Museum and Pacific Film Archive

 Berkeley Art Museum and Pacific Film Archive

Tiny functions for codecs, compilation, and (maybe) soon everything

Colloquium | January 25 | 12-1 p.m. | 430 Soda Hall

 Keith Winstein, Stanford


Networks, applications, and media codecs frequently treat one another as strangers. By expressing large systems as compositions of small, pure functions, we've found it's possible to achieve tighter couplings between these components, improving performance without giving up modularity or the ability to debug. I'll discuss our experience with systems that demonstrate this basic idea: ExCamera...   More >

Keys Track 1a- Principles of Supervision: Setting the Context

Course | January 25 | 12:30-4:30 p.m. | 24 University Hall

 Paul Carroll

 Human Resources

This course will help participants understand the role of the supervisor, and its relationship to the organization. We will focus on what a supervisor needs to know and do, how to use influence when you don’t have control, and the resources available to help you be more effective. We will also look at how to motivate and retain engaged employees. This workshop addresses the following...   More >

Seminar 217, Risk Management: PageRank on directed complex networks

Seminar | January 25 | 12:30-2 p.m. | 1011 Evans Hall

 Speaker: Mariana Olvera-Cravioto, UC Berkeley

 Center for Risk Management Research

The talk will center around a set of recent results on the analysis of Google’s PageRank algorithm on directed complex networks. In particular, it  will focus on the so-called power-law hypothesis, which states that the distribution of the ranks produced by PageRank on a scale-free graph (whose in-degree distribution follows a power-law) also follows a power-law with the same tail-index as the...   More >

ISF 110 - Free Speech in the Public Sphere: An Interdisciplinary Approach

Course | January 16 – May 3, 2018 every Tuesday & Thursday | 2-3:30 p.m. | 102 Wurster Hall

 Division of Undergraduate Education

In this spring 2018 class, we shall take up the nature of public speech from Socrates' public dissent to social media messaging today. The course reading will combine classic philosophical statements about the value of free, subversive and offensive speech; histories of the emergence of public spheres; and sociologies of technologically-mediated speech today.
