Berkeley-Tokyo Summer School "Geometry, Representation Theory, and Mathematical Physics": Mirror symmetry for very affine varieties

Seminar | August 24 | 10-11:30 a.m. | 375 LeConte Hall

 Vivek Shende, UC Berkeley

 Department of Mathematics

Using tropical methods, I will describe the skeleton for the general hyper surface cut out by a Laurent polynomial with only one term in the interior of its newton polytope. This turns out to agree with the skeleton introduced by Fang, Liu, Treumann, and Zaslow. Using the work of Kuwakagi, a new functoriality statement for the coherent-constructible correspondence, and the cosheafification result...   More >

Solid State Technology and Devices Seminar: Non-von Neumann computing using networks of optical parametric oscillators

Seminar | August 24 | 1-2 p.m. | Cory Hall, 540 A/B DOP Center

 Professor Peter McMahon, Stanford University

 Electrical Engineering and Computer Sciences (EECS)

Abstract: Combinatorial optimization problems are central in numerous important application areas, including operations and scheduling, drug discovery, finance, circuit design, sensing, and manufacturing. There is a long history of attempts to find alternatives to current von Neumann-computer-based methods for solving such problems, including neural networks, DNA computing, and most recently...   More >

Berkeley-Tokyo Summer School "Geometry, Representation Theory, and Mathematical Physics": Spaces of stability conditions on the Calabi-Yau categories associated with quivers II

Seminar | August 24 | 1:15-2:45 p.m. | 375 LeConte Hall

 Akishi Ikeda, UC Tokyo

 Department of Mathematics

The aim of this lecture is to introduce the spaces of Bridgeland stability conditions on the Calabi-Yau categories associated with quivers. In the first part, we introduce the space of Bridgeland stability conditions on a triangulated category and review its basic properties. We also see examples of stability conditions. In the second part, we see known results about the spaces of stability...   More >

Getting Started in Undergraduate Research and Finding a Mentor Workshop

Workshop | August 24 | 3-4 p.m. | 9 Durant Hall

 Leah Carroll, Haas Scholars Program Manager/Advisor, Office of Undergraduate Research and Scholarships

 Office of Undergraduate Research

Getting Started in Undergraduate Research

If you are thinking about getting involved in undergraduate research, this workshop is a great place to start! You will get a broad overview of the research opportunities available to undergraduates on campus, and suggestions on how to find them.

We will also let you know about upcoming deadlines and eligibility requirements for some of...   More >

Berkeley-Tokyo Summer School "Geometry, Representation Theory, and Mathematical Physics": Integrability lattice models from four-dimensional gauge theory

Seminar | August 24 | 3:30-5 p.m. | 375 LeConte Hall

 Masahito Yamazaki, IPMU, University of Tokyo

 Department of Mathematics

I will describe my recent work with Kevin Costello and Edward Witten, on explaining integrable models from a four-dimensional gauge theory.

Nonparametric network comparison

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

 Patrick Wolfe, Purdue University

 Department of Statistics

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 >

Introduction to LaTeX using Collaboration Tools

Workshop | August 24 | 4-5 p.m. | Bechtel Engineering Center, Kresge Engineering Library Training Room 110MD

 Anna Sackmann, Science Data and Engineering Librarian, Kresge Engineering Library; Lisa Ngo, Engineering Librarian, Kresge Engineering Library

 Library

This workshop is an introduction to the LaTeX typesetting language. Document structure, templates, and commonly used syntax will be introduced and practiced during this hands-on workshop.

  Registration opens August 4. Register online or by calling Anna Sackmann at 510-642-9478, or by emailing Anna Sackmann at asackmann@berkeley.edu

Mathematics Department Colloquium: Semi-algebraic sets of integer points

Colloquium | August 24 | 4:10-5 p.m. | 60 Evans Hall

 Günter M. Ziegler, Freie Universität Berlin

 Department of Mathematics

We look at sets of integer points in the plane, and discuss possible definitions of when such a set is "complicated"—this might be the case if it is not the set of integer solutions to some system of polynomial equations and inequalities. Let’s together work out lots of examples, and on the way let’s try to develop criteria and proof techniques$\ldots$.

The examples that motivated our...   More >
