### Structural Engineering, Mechanics and Materials Seminar: Optimization Under Uncertainty for Design, Materials, and Large-Scale Computing

Seminar | November 4 | 12-1 p.m. | 502 Davis Hall

James R. Stewart, Computational Sciences & Math Sandia National Laboratories

This presentation highlights the many ways that optimization is used to support multiscale, multiphysics modeling and simulation. Examples include design and topology optimization, as well as PDE-constrained optimization and Bayesian inference for estimating material properties or input model parameters. In the context of additive manufacturing, the materials themselves become part of the design...   More >

A partition of a positive integer n is a non-increasing sequence of positive integers whose sum is n. A Rogers-Ramanujan type identity is a theorem stating that for all n, the number of partitions of n satisfying some difference conditions equals the number of partitions of n satisfying some congruence conditions. In the 1980's, Lepowsky and Wilson established a connection between the...   More >

### Differential Geometry Seminar: Minimal surfaces via Allen-Cahn

Seminar | November 4 | 3-4 p.m. | 939 Evans Hall

Christos Mantoulidis, MIT

We will survey the construction of minimal surfaces (critical points of the area functional) as limits of solutions of the Allen-Cahn equation, $\epsilon ^2 \Delta u = u^3 - u$, with $\epsilon \to 0$. We will focus on Allen-Cahn solutions that arise from min-max constructions, and we'll discuss properties of the corresponding minimal surfaces. Part of this talk is joint work with Otis Chodosh.

### Arithmetic Geometry and Number Theory RTG Seminar: On the Kudla-Rapoport conjecture

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

Chao Li, Columbia

Department of Mathematics

The Kudla-Rapoport conjecture predicts a precise identity between the arithmetic intersection numbers of special cycles on unitary Rapoport-Zink spaces and the derivatives of local representation densities of hermitian forms. It is a key local ingredient to establish the arithmetic Siegel-Weil formula, relating the height of generating series of special cycles on Shimura varieties to the...   More >

### Anil Aswani — Optimization Hierarchy for Fair Statistical Decision Problems

Seminar | November 4 | 3:30-4:30 p.m. | 1174 Etcheverry Hall

Anil Aswani, University of California, Berkeley

Abstract: Data-driven decision-making has drawn scrutiny from policy makers due to fears of potential discrimination, and a growing literature has begun to develop fair statistical techniques. However, these techniques are often specialized to one model context and based on ad-hoc arguments, which makes it difficult to perform theoretical analysis. This paper develops an optimization hierarchy...   More >

### Northern California Symplectic Geometry Seminar: Systoles, Special Lagrangians, and Bridgeland stability conditions

Seminar | November 4 | 4-5 p.m. | 748 Evans Hall

Yu-Wei Fan, UC Berkeley

Department of Mathematics

We propose a question that naturally generalizes Loewner’s torus systolic inequality from the perspective of Calabi-Yau geometry: Is the square of the minimum volume of special Lagrangians in a Calabi-Yau manifold bounded above by the total vol- ume of the Calabi-Yau? We introduce the categorical analogues of systole and volume in terms of Bridgeland stability conditions, which enables us to...   More >

### Winners and Losers?: The Effect of Gaining and Losing Access to Selective Colleges on Education and Labor Market Outcomes

Colloquium | November 4 | 4-5:30 p.m. | Berkeley Way West, Room 1102, Berkeley Way West (2121 Berkeley Way, Berkeley, CA 94720)

Jesse Rothstein, University of California, Berkeley; Department of Economics and Goldman School of Public Policy

(Joint with Sandra Black and Jeffrey Denning)

College admissions processes are fundamentally a question of tradeoffs: given capacity, admitting one student means rejecting another. Research to date has generally estimated average effects of college selectivity, and has been unable to distinguish between the gains to students gaining access and the losses to students losing access. We use the...   More >

### The Lord of the Rings: structural mechanism of a DNA polymerase sliding clamp loader

Seminar | November 4 | 4-5 p.m. | 106 Stanley Hall

Brian Kelch, University of Massachusetts Medical School

College of Chemistry

The sliding clamp Proliferating Cell Nuclear Antigen (PCNA) is a central regulator of genomic integrity and cell proliferation pathways in all eukaryotes. PCNA is a ring-shaped complex that encircles and slides along DNA, serving as an essential cofactor of DNA polymerases and scores of other proteins to coordinate DNA replication with numerous cellular processes. PCNA is installed on DNA by a...   More >

### The Technology Politics of Mechanizing Crops: Insights from California Agriculture, 1945-1985

Seminar | November 4 | 4-5 p.m. | Morgan Hall, Morgan Lounge

This is the age of agricultural robots. Media outlets from the Los Angeles Times to The New Yorker are publishing articles on new robotic advances. The contemporary fascination with robots, artificial intelligence, ‘big data’, and other Silicon-Valley-inspired technology is rooted in a long history of framing automation as natural and inevitable. For the past century, the...   More >

### Analysis and PDE Seminar: A tale of two resolvent estimates

Seminar | November 4 | 4:10-5 p.m. | 939 Evans Hall

Jared Wunsch, Northwestern University

Department of Mathematics

I will discuss two new results concerning the best of resolvent estimates and the worst of resolvent estimates. In the former, case, that of nontrapping obstacles or metrics, we have obtained (in joint work with Galkowski and Spence) optimal, dynamically determined, constants in the standard non-trapping estimate for the (chopped off) resolvent. In the latter case, that of obstacles or metrics...   More >

### ATC Lecture — Guy Hoffman, "Transience, Replication, and the Paradox of Social Robotics"

Colloquium | November 4 | 6:30-8 p.m. | Berkeley Art Museum and Pacific Film Archive, Osher Theater

Guy Hoffman, Robotics Researcher, Cornell University

As we continue to develop social robots designed for connectedness, we struggle with paradoxes related to authenticity, transience, and replication. In this talk, I will attempt to link together 15 years of experience designing social robots with 100-year-old texts on transience, replication, and the fear of dying. Can there be meaningful relationships with robots who do not suffer natural decay?...   More >
