Set Summary Perception, Outlier Pop Out, and Categorization: A Common Underlying Computation?

Seminar | October 29 | 11:10 a.m.-12:30 p.m. | 489 Minor Hall

 Shaul Hochstein, Professor, The Hebrew University of Jerusalem

 Neuroscience Institute, Helen Wills

Recent research has focused on perception of set statistics. Presented briefly with a group of elements, simultaneously or successively, observers report precisely the mean of a variety of set features, but are unaware of individual element values. This has been shown for both low and high level features, from circle size to facial expression. A remaining puzzle is how can the perceptual system...   More >

Children Learning to Collaborate: Cultural Paradigms

Colloquium | October 29 | 12:10-1:30 p.m. | 1102 Berkeley Way West

 Barbara Rogoff, University of California, Santa Cruz

 Department of Psychology

How do children learn to collaborate with others? In this talk, Barbara Rogoff discusses cultural differences in children's collaboration and in supports for learning to collaborate. She argues that collaboration is a key aspect of a cultural paradigm for learning that is especially prevalent in many Mexican and Indigenous-heritage communities of the Americas, where children have wide opportunity...   More >

Combinatorics Seminar: Nonsymmetric Macdonald polynomials and Demazure characters

Seminar | October 29 | 12:10-1 p.m. | 939 Evans Hall

 Sami H. Assaf, University of Southern California

 Department of Mathematics

Macdonald introduced symmetric functions in two parameters that simultaneously generalize Hall—Littlewood symmetric functions and Jack symmetric functions. Opdam and Macdonald independently introduced nonsymmetric polynomial versions of these that Cherednik then generalized to any root system. Sanderson and Ion showed that these nonsymmetric Macdonald polynomials with one parameter specialized...   More >

String-Math Seminar: Coulomb branch integrals and mock modular forms

Seminar | October 29 | 2-3 p.m. | 402 LeConte Hall

 Georgios Korpas, Trinity College Dublin & University of Athens

 Department of Mathematics

We revisit Donaldson-Witten theory, that is the \(N=2\) topologically twisted super Yang-Mills theory with gauge group \(SU(2)\) or \(SO(3)\) on compact 4-manifolds. We study the effective action in the Coulomb branch of the theory and by considering a specific \(Q\)-exact deformation to the theory we find interesting connections to mock modular forms. A specific operator of this theory computes...   More >

Arithmetic Geometry and Number Theory RTG Seminar: Polylogarithms, Chabauty's Method, and the S-Unit Equation

Seminar | October 29 | 3:10-5 p.m. | 748 Evans Hall

 David Corwin, UC Berkeley

 Department of Mathematics

In the first half, we will review Chabauty's and Skolem's methods. We will then explain how these can be generalized to the non-abelian Chabauty's method of Minhyong Kim. If time allows, I will also mention polylogarithms.

In the second half, we will describe work by the speaker and Ishai Dan-Cohen, building on previous work of Brown, Dan-Cohen, and Wewers, that computes with Kim's method in the...   More >

Vision to Action: Towards a Cellular-Resolution Atlas of the Zebrafish Visual and Visuomotor System

Seminar | October 29 | 4-5 p.m. | 125 Li Ka Shing Center

 Herwig Baier, Department Genes – Circuits – Behavior, Max Planck Institute of Neurobiology, 82152 Martinsried, Germany

 Neuroscience Institute, Helen Wills

Understanding brain-wide neuronal dynamics and behavior requires a detailed map of the underlying circuit architecture. We built an interactive cellular-resolution atlas of the zebrafish brain, with a focus on the visual and visuomotor system, and generated from our dataset an inter-areal wiring diagram, which serves as ground truth for synapse-scale, electron microscopic reconstructions. We have...   More >

Seminar 208, Microeconomic Theory: "Games of Love and Hate"

Seminar | October 29 | 4-5:30 p.m. | 639 Evans Hall

 Rajiv Vohra, Brown

 Department of Economics

Co-Authored with Debraj Ray

Analysis and PDE Seminar: Wave maps on (1+2)-dimensional curved spacetimes

Seminar | October 29 | 4:10-5 p.m. | 740 Evans Hall

 Casey Jao, UCB

 Department of Mathematics

I will discuss recent joint work, with Cristian Gavrus and Daniel Tataru, in which we consider wave maps on a (1+2)-dimensional nonsmooth background. Our main result asserts that in this variable-coefficient context, the wave maps system is wellposed at almost-critical regularity.

Deformation Theory Seminar: $A_\infty $ and differential graded algebras

Seminar | October 29 | 5:10-6:30 p.m. | 891 Evans Hall

 Meredith Shea, UC Berkeley

 Department of Mathematics

We will review the theory of $A_\infty $-algebras, their minimal models and differential graded realizations. We discuss the example of the Ext algebra which arises in Koszul duality.
