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 strategies for connecting with faculty members who can guide you.

### Deep Learning Methodologies and Tools for Scientific Problems: Berkeley Fluids Seminar

Seminar | September 16 | 12-1 p.m. | 3110 Etcheverry Hall

Chiyu “Max” Jiang, Ph.D. Student, Department of Mechanical Engineering, University of California, Berkeley

Department of Mechanical Engineering (ME)

Abstract: Modern tools in machine learning and deep learning can offer new insights to old problems, both on the methodological side as well as on the technical side. The first half of this talk will present an overview of tools and subfields in geo¬metric deep learning that are particularly relevant and applicable to physical problems, (e.g., learning on regular grids, meshes/graphs and point...

### Combinatorics Seminar: Logarithmic concavity for morphisms of matroids

Seminar | September 16 | 12:10-1 p.m. | 939 Evans Hall

Christopher Eur, UC Berkeley

Morphisms of matroids are combinatorial abstractions of linear maps and graph homomorphisms. We introduce the notion of basis for morphisms of matroids, and show that its generating function is strongly log-concave. As a consequence, we obtain a generalization of Mason's conjecture on the f-vectors of independent subsets of matroids to arbitrary morphisms of matroids. To establish this, we define... More >

### PERL Seminar: “Productivity, Pay, and Sectoral Choice: The Labor Market of School Principals”

### Introduction to Crowdsourcing in Research: Overview of Processes and Discussion on Benefits and Concerns

Workshop | September 16 | 1-3 p.m. | Barrows Hall, Room 371

Kate Beck, Progam Lead, UC Berkeley SafeTREC

Safe Transportation Research & Education Center

Crowdsourcing is a method increasingly used in qualitative, quantitative, and mixed-methods research. However, many researchers remain unclear about what this method is, when it may be appropriate to use, and how it could be implemented. Please join Kate Beck, Program Lead at UC Berkeley's Safe Transportation Research and Education Center (SafeTREC), to learn more about this research... More >

### Contemplating Gratitude: Photography Workshop

Workshop | September 16 | 1-4 p.m. | UC Botanical Garden

When we observe Nature through the lens of ecology, we see the exquisite interconnectedness of all life. In this contemplative photography workshop, we will devote our attention to connectedness and interconnectedness, using the camera as a tool for meditation and the garden as our muse.

Any and all equipment are invited, including DSLRs, mobile phones, point-and-shoot, polaroid, and pinhole... More >

### String-Math Seminar: A taste of microlocal Hodge theory

Seminar | September 16 | 2-3 p.m. | 402 LeConte Hall

Michael McBreen, University of Toronto

The nonabelian Hodge correspondence gives a diffeomorphism between the moduli of flat connections and the moduli of higgs bundles on a smooth Riemann surface. The two moduli, however, are completely different as algebraic varieties. Thus natural structures on one side of the correspondence, such as Hitchin's integrable system, become rather mysterious on the other side.

I will discuss joint work... More >

### Seminar 211, Economic History: Intergenerational Mobility of Immigrants in the US over Two Centuries

Seminar | September 16 | 2-3:30 p.m. | 597 Evans Hall

Ran Abramitzky, Stanford University

### Probabilistic Operator Algebra Seminar: Triangular Transport for Free Gibbs Laws from Convex Potentials

Seminar | September 16 | 3-5 p.m. | 736 Evans Hall

David Andrew Jekel, UCLA

We study tuples $(X_1,\dots ,X_m)$ of self-adjoint operators in a tracial $W^*$-algebra whose non-commutative distribution is free the Gibbs law for a (sufficiently regular) convex potential $V$. Such tuples model the large $N$ behavior of random matrices $(X_1^{(N)}.\dots ,X_m^{(N)}$ chosen according to the measure $e^{-N^2 V(x)}\,dx$ on $M_N( \mathbb C)_{sa}^m$. Previous work showed that...

### Differential Geometry Seminar: Semi-local simple connectedness of non-collapsing Ricci limit spaces

Seminar | September 16 | 3-4 p.m. | 939 Evans Hall

Jiayin Pan, UCSB

We prove that any non-collapsing Ricci limit space is semi-locally simply connected. This is joint work with Guofang Wei.

### Arithmetic Geometry and Number Theory RTG Seminar: Distributions of unramified extensions of global fields

Seminar | September 16 | 3:10-5 p.m. | 740 Evans Hall | Note change in location

Melanie Matchett Wood, UC Berkeley

We give conjectures on the distribution of the Galois groups of the maximal unramified extensions of Galois Γ-number fields or function fields for any finite group Γ (for the part of the Galois group prime to the order of Γ and the order of roots of unity in the base field). We explain some results about these Galois groups that motivate us to build certain random groups whose distributions... More >

### Seminar 271, Development: The Effects of Joining Multinational Supply Chains: New Evidence from Firm-to-Firm Linkages

Seminar | September 16 | 4-5:30 p.m. | 648 Evans Hall

Isabela Manelici, UC Berkeley, Economics

### Emergent Dynamic Structures in Everyday Life: Contexts for Situated Action

Colloquium | September 16 | 4-5:30 p.m. | Berkeley Way West, Room 1102, Berkeley Way West (2121 Berkeley Way, Berkeley, CA 94720)

Harry Heft, Denison University

From the perspective of ecological psychology, perception–action processes are coupled to relational environmental structures at the level of affordances and dialogical exchanges. Less often realized is that they are also embedded within identifiable higher-order, dynamic, eco-psychological structures that emerge from joint action among individuals in the course of daily life. These dynamic,... More >

### Chemical Proteomic Platforms to Expose and Exploit Novel Metabolic Signals in Disease

Seminar | September 16 | 4-5 p.m. | 106 Stanley Hall

Raymond Moellering, The University of Chicago

Biological systems are inherently and profoundly heterogeneous, both at the molecular level (e.g. encoded proteins existing in distinct posttranslational modification states) and the cellular level (e.g. organization of biomolecules to distinct regions of a cell or distinct cells within a tissue). Therefore, in order to understand information flow under basal or diseased states we must be able to... More >

### Seminar 208, Microeconomic Theory (Practice Job Talk): "Constrained Allocation Mechanisms"

Seminar | September 16 | 4:10-5:30 p.m. | 639 Evans Hall

Joseph Root, UC Berkeley

### Analysis and PDE Seminar: On the Cauchy problem for the Hall-magnetohydrodynamics equations

Seminar | September 16 | 4:10-5 p.m. | 939 Evans Hall

Sung-Jin Oh, UC Berkeley

In this talk, I will describe a recent series of work with I.-J. Jeong on the Cauchy problem for the Hall-MHD equation without resistivity. This PDE, first investigated by the applied mathematician M. J. Lighthill, is a one-fluid description of magnetized plasmas with a quadratic second-order correction term (Hall current term), which takes into account the motion of electrons relative to... More >

### Supersymmetry and Dark Matter: From the Weak Scale to the Planck Scale

Colloquium | September 16 | 4:15-5:15 p.m. | LeConte Hall, 1 LeConte

Dr. Keith Olive, University of Minnesota

While supersymmetry remains an interesting and important extension of the Standard Model of particle interactions, it experimental verification remains elusive. There are many motivations for supersymmetry, many of which center on the notion of Grand Unification. However, motivations for supersymmetry do not necessarily point to weak scale supersymmetry. I will review the prospects for weak scale... More >

### Patrick Martinez: Excavations of Recent History

Presentation | September 16 | 6:30 p.m. | Berkeley Art Museum and Pacific Film Archive

Berkeley Art Museum and Pacific Film Archive

Patrick Martinez is a multidisciplinary artist who creates works that act as excavations of language, belonging, and the visual-cultural systems of the city of Los Angeles, in order to create dialogues concerning the ongoing residue of gentrification. Throughout his practice, he uses materials and modes of address recognizable within neighborhoods that face the threat of removal and erasure—neon... More >
