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
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
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
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
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
I will describe my recent work with Kevin Costello and Edward Witten, on explaining integrable models from a four-dimensional gauge theory.
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 >
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
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.
Colloquium | August 24 | 4:10-5 p.m. | 60 Evans Hall
Günter M. Ziegler, Freie Universität Berlin
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 >
