Manipulating Intraocular Pressure as a Novel Avenue for Controlling Myopia Progression

Myopia (near-sightedness) results from progressive, excessive eye enlargement and is associated with blinding complications. It has become a significant public health concern, reaching epidemic levels in some parts of the world. The eye is like a balloon, with pressure inside the eye... More >

### Combinatorics Seminar: The Hopf monoid of orbit polytopes and its character group

Seminar | October 22 | 12:10-1 p.m. | 939 Evans Hall

Mariel Supina, UC Berkeley

A Hopf monoid is an algebraic structure that many families of combinatorial objects share. The collection of multiplicative functions defined on a Hopf monoid forms a group, called the character group. Aguiar and Ardila (2017) proved that the character groups for the Hopf monoids of permutahedra and associahedra are exponential power series under multiplication and composition, respectively. In...

### Political Economy Seminar: "The Long-lasting Effects of Living Under Communism on Financial Risk-Taking"

Seminar | October 22 | 12:30-2 p.m. | 223 Moses Hall

Ulrike Malmendier, UC Berkeley

The Political Economy Seminar focuses on formal and quantitative work in the political economy field, including formal political theory.

### String-Math Seminar: 3D TQFTs from Argyres-Douglas theories

Seminar | October 22 | 2-3 p.m. | 402 LeConte Hall

Mykola Dedushenko, Caltech

I will describe a construction which, for a given \(4d\), \(N=2\) Argyres-Douglas SCFT, seems to produce a three-dimensional TQFT, whose underlying modular tensor category coincides with that of a \(2d\) chiral algebra of the parent \(4d\), \(N=2\) theory.

### Arithmetic Geometry and Number Theory RTG Seminar: On Shimura varieties for unitary groups

Seminar | October 22 | 3-5 p.m. | 748 Evans Hall

Brian Smithling, Johns Hopkins

Shimura varieties attached to unitary similitude groups are a well-studied class of PEL Shimura varieties (i.e., varieties admitting a moduli description in terms of abelian varieties endowed with a polarization, endomorphisms, and a level structure). There are also natural Shimura varieties attached to (honest) unitary groups; these lack a moduli interpretation, but they have other advantages... More >

### Ashwini Deo, "Marathi tense marking: A window into the lexical encoding of tense meanings"

Colloquium | October 22 | 3:10-5 p.m. | 370 Dwinelle Hall

Ashwini Deo, The Ohio State University

Partee (1973) first observed that natural language tense expressions are analogous to pronouns in that they can be interpreted indexically, anaphorically, and like bound variables. These referential (i.e. indexical+anaphoric) and non-referential interpretations of tense marking have not been yet shown to have distinct reflexes in natural language temporal expressions – i.e. no language has been...

### Differential Geometry Seminar: Harmonic Z/2 spinors and wall-crossing in Seiberg-Witten theory

Seminar | October 22 | 3:10-4 p.m. | 939 Evans Hall

Aleksander Doan, Stony Brook

The notion of a harmonic Z/2 spinor was introduced by Taubes as an abstraction of various limiting objects appearing in compactifications of gauge-theoretic moduli spaces. I will explain this notion and discuss an existence result for harmonic Z/2 spinors on three-manifolds. The proof uses a wall-crossing formula for solutions of generalized Seiberg-Witten equations in dimension three, a result... More >

### Seminar 271, Development: "Credit Lines as Insurance: Evidence from Bangladesh"

Seminar | October 22 | 4-5:30 p.m. | 648 Evans Hall

Greg Lane, UC Berkeley, ARE

### Global warming: What you need to know, what people actually know, and how to bridge the gap

Colloquium | October 22 | 4-5:30 p.m. | 1215 Berkeley Way West

David Romps, Physical Sciences and the Berkeley Atmospheric Sciences Center, UC Berkeley, and the Lawrence Berkeley National Laboratory

Abstract. Global warming is the most urgent issue of our time: coal, oil, and gas are being burned at an all-time record rate; as a result, the air that we breathe is filling up with carbon dioxide faster than ever before; in response, the Earth is heating rapidly; and both the carbon-dioxide pollution and the associated heating are permanent on any timescale of human interest. How well have... More >

### Design Field Notes: Diane Wang

Seminar | October 22 | 4-5 p.m. | 220 Jacobs Hall

Jacobs Institute for Design Innovation

Diane Wang is a Lead UX Designer at Google’s Daydream Labs, leading rapid prototyping efforts for AR/VR.

### Seminar 208, Microeconomic Theory: "Ambiguous Persuasion"

Seminar | October 22 | 4-5:30 p.m. | 639 Evans Hall

Co-Authored with Dorian Beauchene and Ming Li

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

Seminar | October 22 | 4:10-5 p.m. | 740 Evans Hall | Canceled

Casey Jao, UC Berkeley

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

### Deformation Theory Seminar: Operads and Koszul duality

Seminar | October 22 | 5:10-6:30 p.m. | 891 Evans Hall

Yixuan Li, UC Berkeley

In this talk we'll introduce operads and the interaction with sheaf theory. Parallel to the notion of Koszul algebras, we'll define Koszul operads and duality between them. In particular, connections with sheaves and Verdier duality will be explained in an example arising from the moduli spaces of genus zero stable curves with marked points.

### SLAM: Perspectives from Biotech Industry: Science, Business and People

Seminar | October 22 | 5:30-6:30 p.m. | 106 Stanley Hall

Dr. Janet Gunzner, Nektar Therapeutics

### Let's Talk About Sex!: A Graduate Student Sexual Education Series

Workshop | October 22 | 6-7:30 p.m. | 183 Dwinelle Hall

Graduate Student Wellness Project, Sexual Health Education Program

The Graduate Student Wellness Group and the Sexual Health Education Program are partnering up for three sextastic events this October! Topics include (but are not limited to) consent, healthy relationships, safer sex, STIs/HIV, and accessing birth control! Specifically, we will be addressing what healthy relationships look/don't look like, why STIs are on the rise, how to practice safer sex, and... More >
