Charles-Albert Lehalle - Closing The Loop of Optimal Trading: a Mean Field Game of Controls

Seminar | April 24 | 10:30 a.m.-12 p.m. | 4193 Etcheverry Hall

 Charles-Albert Lehalle, Université Pierre et Marie Curie (Paris VI)

 Industrial Engineering & Operations Research

This talk explains how to formulate the now classical problem of optimal liquidation (or optimal trading) inside a Mean Field Game (MFG). This is a noticeable change since usually mathematical frameworks focus on one large trader in front of a " background noise " (or " mean field "). In standard frameworks, the interactions between the large trader and the price are a temporary and a permanent...   More >

Combinatorics Seminar: Combinatorial evaluation of Hecke algebra traces

Seminar | April 24 | 11:10 a.m.-12 p.m. | 939 Evans Hall

 Mark Skandera, Lehigh University

 Department of Mathematics

(Please note the unusual time of this talk.)

The (type A) Hecke algebra $H_n(q)$ is a certain module over $\mathbb Z[q^{1/2},q^{-1/2}]$ which is a deformation of the group algebra of the symmetric group. The $\mathbb Z[q^{1/2},q^{-1/2}]$-module of its trace functions has rank equal to the number of integer partitions of $n$, and has bases which are natural deformations of those of the symmetric...   More >

Dimensional Reduction and Hyper Reduction of Parametric Nonlinear Structural Dynamics Models for Real-Time Computing: SEMM Seminar

Seminar | April 24 | 12-1 p.m. | 502 Davis Hall

 Charbel Farhat, Professor, Department of Aeronatics and Astronautics, Department of Mechanical Engineering and Institute for Computational and Mathematical Engineering, Stanford University

 Civil and Environmental Engineering (CEE)

Model reduction is a tool in applied mathematics that is rapidly becoming indispensable for computational-based design and optimization, stochastic analysis for uncertainty quantification, embedded computing, and online optimal control. It is also essential for “what-if” engineering scenarios and other parametric studies where dramatically faster if not real-time simulation responses are desired.

Combinatorics Seminar: Counting monochromatic structures in finite abelian groups

Seminar | April 24 | 12:10-1 p.m. | 939 Evans Hall

 Julia Wolf, University of Bristol

 Department of Mathematics

It is well known (and a result of Goodman) that a random 2-colouring of the edges of the complete graph $K_n$ contains asymptotically the minimum number of monochromatic triangles ($K_3$s). Erdős conjectured that this was also true of monochromatic copies of $K_4$, but his conjecture was disproved by Thomason in 1989. The question of determining for which small graphs Goodman's result holds true...   More >

Reading Technopoetic Japan

Colloquium | April 24 | 2:30 p.m. | 142 Dwinelle Hall

 Earl Jackson Jr., National Chiao Tung University

 Center for Japanese Studies (CJS), Department of Comparative Literature, Film & Media Studies

What is often dismissed as “otaku culture” actually names a complex network of creative industries and equally creative engaged participants. The media that emerge and sustain these subcultural formations include anime, manga, novels, etc.. In studying these media I focus on relations among technology, representation, and subjectivity as well as the politics that inform and circumscribe those...   More >

Probabilistic Operator Algebra Seminar: Trace formulas in perturbation theory

Seminar | April 24 | 3-5 p.m. | 736 Evans Hall

 Anna Skripka, University of New Mexico, Albuquerque

 Department of Mathematics

In this talk I will present trace formulas arising in perturbation theory that substantially extend the celebrated Krein's result of the 50s. These formulas provide representations for remainders of approximations of operator functions that "split up" the involved noncommutativity. Proofs of the results rely on a fascinating theory of multiple operator integration that has been developing for...   More >

Student Algebraic Geometry Seminar: Computations in Local Rings using Macaulay2

Seminar | April 24 | 4-5 p.m. | 891 Evans Hall

 Mahrud Sayrafi, UC Berkeley

 Department of Mathematics

Local rings are ubiquitous in algebraic geometry. Not only are they naturally meaningful in a geometric sense, but also they are extremely useful in proving theorems. When studying finitely generated modules over local rings, for instance, projectivity, flatness, and freeness are all equivalent. Above all, many important results depend on Nakayama's lemma, which holds over local rings. In this...   More >

BLISS Seminar: Geometric optimization: convex and nonconvex

Seminar | April 24 | 4-5 p.m. | 400 Cory Hall

 Suvrit Sra, MIT

 Electrical Engineering and Computer Sciences (EECS)

In this talk, I will highlight some aspects of geometry and its role in optimization. In particular, I will talk about optimization problems whose parameters are constrained to lie on a manifold or in a specific metric space. These geometric constraints often make the problems numerically challenging, but they can also unravel properties that ensure tractable attainment of global optimality for...   More >

China’s Economic Statecraft Toward Myanmar and North Korea

Colloquium | April 24 | 4-6 p.m. | 180 Doe Library

 James Reilly, Government and International Relations, University of Sydney

 Kevin O'Brien, Political Science, UC Berkeley

 Center for Chinese Studies (CCS), Institute of East Asian Studies

Tempted by their expansive authority over China’s economy, Chinese leaders are increasingly deploying economic resources such as foreign aid and overseas investments to influence policy decisions in other countries. To implement economic statecraft, China’s leaders rely upon state-owned companies, bureaucratic agencies, and local Chinese officials, even though they may be unreliable...   More >

Abstract. Environmental education—a diverse field focused on lifelong learning, systems thinking, and sustainability practices—can address a range of outcomes, including environmental knowledge and attitudes, interpersonal skills, and environmentally related behaviors. Many environmental education programs, particularly those with residential or youth-development elements, emphasize...   More >
