### From family research to family policy

Colloquium | January 28 | 12:10-1:15 p.m. | 1102 Berkeley Way West

Phil and Carolyn Cowan, Institute of Human Development

Institute of Human Development

Phil Cowan is a Professor of Psychology, Emeritus, and Carolyn Cowan is a Professor of Psychology, Emerita at UCB. They are both longtime members of IHD. Beginning in the 1970s, they have pioneered a preventive intervention approach to strengthening family relationships. Although the prevailing strategy for facilitating children's development has been parenting classes (attended mostly by...   More >

### Combinatorics Seminar: Triangulations with vanishing local h-polynomials

Seminar | January 28 | 12:10-1 p.m. | 939 Evans Hall

Sam Payne, MSRI and University of Texas at Austin

Department of Mathematics

Twenty-five years ago, Stanley introduced local h-polynomials for subdivisions of simplices, proved that the coefficients are non-negative integers, and posed the problem of characterizing triangulations for which this invariant vanishes. The work I will present is motivated by potential applications in other areas of mathematics (local h-polynomials now appear prominently in both algebraic and...   More >

### Political Economy Seminar: "Endogenous Intractability: Why Some Persistent Problems Persist"

### Ozge Yapar - Bayesian Sequential Learning for Clinical Trials of Multiple Correlated Medical Interventions

Seminar | January 28 | 1-2:30 p.m. | Haas School of Business, Chou Hall N370

Ozge Yapar, University of Pennsylvania

Abstract: We integrate emerging trends intended to improve clinical trial design: design for cost-effectiveness, which ensures health-economic improvement of a new intervention over the current standard intervention; adaptive design, which dynamically adjusts the sample size and allocation of patients to different interventions; and multi-arm trial design, which compares multiple interventions...   More >

### String-Math Seminar: q-Opers, q-Langalnds and Classical/Quantum duality

Seminar | January 28 | 2-3 p.m. | 402 LeConte Hall

Peter Koroteev, UC Berkeley

Department of Mathematics

A special case of the geometric Langlands correspondence is given by the relationship between solutions of the Bethe ansatz equations for the Gaudin model and opers - connections on the projective line with extra structure. We describe a deformation of this correspondence for $$SL(N)$$. We introduce a difference equation version of opers called q-opers and prove a q-Langlands correspondence...   More >

### Probabilistic Operator Algebra Seminar: An Elementary Approach to Free Gibbs States with Convex Potentials

Seminar | January 28 | 2-4 p.m. | 736 Evans Hall

David Andrew Jekel, UCLA

Department of Mathematics

We present an alternative approach to the theory of free Gibbs states with convex potentials. Instead of solving SDE's, we combine PDE techniques with a notion of asymptotic approximability by trace polynomials for a sequence of functions on $M_N(\mathbb C)_{sa}^m$ to prove the following. Suppose $\mu _N$ is a probability measure on $M_N(\mathbb C)_{sa}^m$ given by uniformly convex and...   More >

### Introduction to NIH Grants

Workshop | January 28 | 2:10-4 p.m. | 356 Barrows Hall

Leora Lawton, Berkeley Population Center

Berkeley Population Center

This workshop will be open to anyone interested in having the guidance, feedback and structure for writing a grant. Potential participants could be faculty who have not written an NIH grant before, postdocs or adjunct faculty, advanced graduate students, or even early stage graduate students who want to put together a dissertation grant. The basic process and the structure of grant applications...   More >

### Getting Started in Undergraduate Research and Finding a Mentor Workshop

Workshop | January 28 | 3-4 p.m. | 9 Durant Hall

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

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 >

### Arithmetic Geometry and Number Theory RTG Seminar: An arithmetic enrichment of the degree of a finite map, and applications to enumerative geometry

Seminar | January 28 | 3-5 p.m. | 748 Evans Hall

Kirsten Wickelgren, Georgia Tech

Department of Mathematics

Using the Eisenbud–Khimshiashvili–Levine local degree, which is the A1-local degree of Morel in A1-homotopy theory, we define a degree of a finite map between smooth schemes over k. When the target is appropriately connected, this degree is a bilinear form over k. We discuss some applications to enumerative geometry over non-algebraically closed fields. This is joint work with Jesse Kass and...   More >

### Differential Geometry Seminar: Stability and Nonlinear PDE in mirror symmetry

Seminar | January 28 | 3:10-4 p.m. | 939 Evans Hall

Tristan Collins, MIT

Department of Mathematics

A longstanding problem in mirror symmetry has been to understand the relationship between the existence of solutions to certain geometric nonlinear PDES (the special Lagrangian equation, and the deformed Hermitian-Yang-Mills equation) and algebraic notions of stability, mainly in the sense of Bridgeland. I will discuss progress in this direction through ideas originating in infinite dimensional...   More >

### Paul Glasserman - Does Unusual News Forecast Market Stress?

Seminar | January 28 | 3:30-4:30 p.m. | 1174 Etcheverry Hall

Paul Glasserman, Columbia University

Abstract: Applying sentiment analysis to news articles on large financial companies, we find that an increase in “unusual” negative news predicts an increase in stock market volatility and thus potential market stress. Similarly, unusual positive news forecasts lower volatility. Our analysis is based on more than 360,000 articles on 50 large financial companies, published in 1996–2014....   More >

### The Feminist Resistance to the Radical Right in Brazil: A Forum of Four Brazilian Feminist Political Leaders

Panel Discussion | January 28 | 4-7 p.m. | Boalt Hall, School of Law, Booth Auditorium (Room 175)

Department of Anthropology

On the eve of entering office, four female politicians are an emboldened, new generation of feminist officials at the forefront of defending and redefining democracy in Brazil. Building their trajectories out of local grassroots struggles, each has developed distinct approaches in their respective states. Ten months following the assassination of city councilwoman Marielle Franco, their...   More >

### From Data Collectors to Data Producers: Shifting students’ relationship to data

Colloquium | January 28 | 4-5:30 p.m. | Berkeley Way West, Room 1215 (2121 Berkeley Way, Berkeley, CA 94704)

Dr. Lisa Hardy, Concord Consortium

Outside of school, students will encounter and be asked to interpret data and data representations that they did not create themselves — often with limited information about why or how these data were constructed in the first place. In contrast, studies of science practice highlight that the interpretation of data is strongly contingent on the context in which that data was produced. Data can...   More >

### Support points – a new way to reduce big and high-dimensional data

Seminar | January 28 | 4-5 p.m. | 1011 Evans Hall

Simon Mak, Georgia Institute of Technology

Department of Statistics

This talk presents a new method for reducing big and high-dimensional data into a smaller dataset, called support points (SPs). In an era where data is plentiful but downstream analysis is oftentimes expensive, SPs can be used to tackle many big data challenges in statistics, engineering and machine learning. SPs have two key advantages over existing methods. First, SPs provide optimal and...   More >

### Seminar 208, Microeconomic Theory: A Rudimentary Index of Strategic Stability: Deterring Defectors, Sustaining Loyalists and Forming Equilibrium

Seminar | January 28 | 4-5:30 p.m. | 639 Evans Hall

Ehud Kalai

Department of Economics

A rudimentary index explains Nash-equilibrium choices observed in behavioral economics.

The index assigns stability levels = 0; 1; :::; n, to strategy profiles of n-person games: Level 0 is assigned to profiles that are not Nash equilibrium, levels are assigned to Nash equilibria in increasing levels of stability, and level n is assigned to dominant-strategy equilibria.

The index measures...   More >
