### Seminar 217, Risk Management: Nonstandard Analysis and its Application to Markov Processes

Seminar | September 18 | 11 a.m.-12:30 p.m. | 1011 Evans Hall

Speaker: Haosui Duanmu, UC Berkeley

Consortium for Data Analytics in Risk

Nonstandard analysis, a powerful machinery derived from mathematical logic, has had many applications in probability theory as well as stochastic processes. Nonstandard analysis allows construction of a single object - a hyperfinite probability space - which satisfies all the first order logical properties of a finite probability space, but which can be simultaneously viewed as a...

### Learning Representations for Planning

Seminar | September 18 | 12-1 p.m. | 560 Evans Hall

Aviv Tamar, Postdoc, UC Berkeley's Artificial Intelligence Research Lab

Neuroscience Institute, Helen Wills

Abstract:

How can we build autonomous robots that operate in unstructured and dynamic environments such as homes or hospitals?

This problem has been investigated under several disciplines, including planning (motion planning, task planning, etc.), and reinforcement learning. While both of these fields have witnessed tremendous progress, each have fundamental drawbacks when it comes to... More >

### Home Ownership (BEUHS341)

Workshop | September 18 | 12:10-1:30 p.m. | Tang Center, University Health Services, Section Club

Thinking about purchasing your first or second home? Considering refinancing your current home loan?

This workshop covers many important topics related to homeownership, including

• Is now the right time to buy a home?

• How much can I afford?

• Are any low cash down payment options available?

• What are first-time homebuyer programs available?

• How do I get pre-approved for a loan?

•... More >

### Seminar 218, Psychology and Economics: Incentivized Resume Rating: Eliciting the Distribution of Employer Preferences without Deception

Seminar | September 18 | 2-3:30 p.m. | 648 Evans Hall

Corinne Low, The Wharton School, University of Pennsylvania

### 3-Manifold Seminar: Symplectic structures on representation varieties of surfaces

Seminar | September 18 | 2:10-3:30 p.m. | 939 Evans Hall

Ian Agol, UC BERKELEY

We'll discuss the symplectic structure on representation varieties of surfaces. Then we'll discuss certain Hamiltonian actions on subsets determined by twists along simple curves.

### Seminar 237, The Macroeconomic Implications of Corporate Debt Policies and Pricing Strategies

Seminar | September 18 | 2:10-3:30 p.m. | 597 Evans Hall

Christian Jauregui, UC - Berkeley

This paper studies the effect of bank lending frictions on firms' corporate debt choices and behaviors in product markets, whereby debt composition consists of bank loans and (market-based) bond issuances. I document a hump-shaped relationship between a firm's reliance on market financing and its product (price-marginal) cost markup: on average, markups rise with their share of market debt in...

### Probabilistic Operator Algebra Seminar: Tensor decompositions of II$_1$ factors arising from extensions of amalgamated free product groups

Seminar | September 18 | 3:45-5:45 p.m. | 748 Evans Hall

Rolando de Santiago, UC Presidential Postdoctoral Fellow, UCLA

We describe a family of groups whose von Neumann algebras satisfy the following rigidity phenomenon: all tensor decompositions of $L(\Gamma )$ into II$_1$ factors necessarily arise from direct product decompositions of the group Γ. This class includes many iterated amalgamated free product groups such as right-angled Artin groups, Burger-Mozes groups, Higman group, integral two-dimensional... More >

### Commutative Algebra and Algebraic Geometry: The Fellowship of the Ring: Curves of genus 11 with several maps of degree 6 to $\mathbb P^1$

Seminar | September 18 | 3:45-4:45 p.m. | 939 Evans Hall

Frank-Olaf Schreyer, MSRI, Universität des Saarlandes

Green's conjecture says that vanishing syzgies of a canonical curve is equivalent to the non-existence of certain linear series on the curve. Turning things around, we might hope that many syzygies imply the existence of many linear systems. In this talk I will survey our knowledge on syzygies of canonical curves and then report on work of Hanieh Keneshlou, who used this approach to study the... More >

### Seminar 281: International Trade and Finance, "Title: "Credit Allocation under Banking Globalization: Theory and Empirics"

Seminar | September 18 | 4-5:30 p.m. | 597 Evans Hall

Abstract:

This paper studies how the globalization of banking affects credit allocation across firms. I develop a model of global and local banking where each type of bank faces a problem of asymmetric information: global banks have the technology to extract global but not local information; local banks have the technology to extract local but not global information. The model shows that this... More >

### Sandia National Laboratories career fair

Career Fair | September 18 | 4-6 p.m. | Etcheverry Hall, Room 3110

Sandia National Laboratories will be on campus! BRING RESUMES! For all interested B.S., M.S. and Ph.D. engineering and science students.

Many positions open for internships, co-ops, and full-time employment.

Most positions require U.S. Citizenship

### Studies of radicals, clusters, and transition states by slow electron velocity-map imaging of cryogenically cooled anions (cryo-SEVI)

Seminar | September 18 | 4-5 p.m. | 120 Latimer Hall

### How to Email a Professor to Get a Positive Response: Workshop

Workshop | September 18 | 4-5 p.m. | 9 Durant Hall

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

Office of Undergraduate Research

Do you need to email a professor you've never met before to ask for their help, but you don't know where to start? Have you ever written a long email to a professor, only to receive no response, or not the one you hoped? If so, this workshop is for you! We will discuss how to present yourself professionally over email to faculty and other professionals ... More >

### Seminar 221, Industrial Organization: "Attention Oligopoly"

Seminar | September 18 | 4:10-5:30 p.m. | 648 Evans Hall

Andrea Prat, Columbia University

### Commutative Algebra and Algebraic Geometry: The Fellowship of the Ring: Curves on surfaces with ordinary singularities in $\mathbb P^3$

Seminar | September 18 | 5-6 p.m. | 939 Evans Hall

Mengyuan Zhang, UC Berkeley

We study curves in $\mathbb P^3$ lying on hypersurfaces that arise as images of “general” maps from smooth surfaces. We describe the numerical invariants of a large class of curves on these surfaces, and study the families of such curves in the Hilbert scheme.

### International Student Career Success Series: Identifying international student friendly hiring employers

Workshop | September 18 | 6-7 p.m. | Career Center (2440 Bancroft Way), Gold Room

Employers' recruiting needs are complicated and always changing, so there is not a clear list of which employers in the US are currently considering international students for their positions. However, there are resources to research and identify employers who sponsored international students with job visas or hired int'l students on CPT or OPT in the past. It will be helpful for you to focus on... More >
