Civil and Environmental Engineering Department Seminar: Recent Advances in Infrastructure and Geosystems Resiliency empowered by Autonomy

Seminar | April 29 | 10-11 a.m. | 542 Davis Hall

 Dimitrios Zekkos

 Civil and Environmental Engineering (CEE)

Autonomy has the capacity to revolutionize the way we protect the natural environment and how we design, build and monitor infrastructure and geo-systems. Advances in data sensing and analysis, artificial intelligence, and robotics pave new avenues for full-scale, system-level infrastructure monitoring and operation. Unmanned aerial vehicles (UAV) equipped with optical sensors are already...   More >

STROBE Seminar: Nanotip photoemitters and THz-antennas for ultrafast imaging on the nanoscale

Seminar | April 29 | 11:45 a.m.-1 p.m. | 775A Tan Hall

 Dr. Melanie Mueller

 STROBE

The STROBE Seminar series is open to all students.
Speaker Abstract:
Understanding the spatio-temporal response of photoexcited nanostructures, low-dimensional systems and molecules at surfaces on their natural length and time scales is a key goal in surface dynamics. Many ultrafast techniques are available to probe the temporal evolution of the photoexcited state. Most approaches, however,...   More >

Combinatorics Seminar: Representations of Hecke algebras and lattice-path counting

Seminar | April 29 | 12:10-1 p.m. | 939 Evans Hall

 Jose Simental Rodriguez, UC Davis

 Department of Mathematics

The branching rule for representations of the symmetric group tells us that, over a field of characteristic zero, the dimension of the irreducible representation indexed by a partition λ is given by the number of directed lattice paths from λ (though of as an integer vector) to the origin that stay inside the dominant Weyl chamber. Over a field of positive characteristic (or for Hecke algebras...   More >

Political Economy Seminar

Workshop | April 29 | 1-4 p.m. | 2251 College (Archaeological Research Facility), Meet in Atrium and move outside building

 Archaeological Research Facility

We’ll meet in the ARF Atrium and, weather permitting, we’ll go outside with the units. The total stations are our Sokkia SET 5 series that are typically used for precision mapping during excavation.

 Workshops cost $50 for non-UC attendees. The workshops are free for students, faculty, and staff. Register online

Dissertation Talk: Optoelectronics for refrigeration and analog circuits for combinatorial optimization

Presentation | April 29 | 1-2 p.m. | 540AB Cory Hall

 Tianyao Xiao, PhD candidate, Department of EECS, UC Berkeley

 Electrical Engineering and Computer Sciences (EECS)

In this dissertation talk, I will cover two topics. First, I will discuss the prospects of using light-emitting diodes as solid-state refrigerators. Second, I will present a non-von Neumann computer, built from coupled analog electrical oscillators, that can rapidly search for solutions to difficult combinatorial optimization problems.

Seminar 231, Public Finance: "Consumption Taxes, Redistribution and Informality"

Seminar | April 29 | 2-3:30 p.m. | 597 Evans Hall

String-Math Seminar: Conformal Limits and Stratifucations

Seminar | April 29 | 2-3 p.m. | 402 LeConte Hall

 Brian Collier, University of Maryland

 Department of Mathematics

Both the Higgs bundle moduli space and the moduli space of flat connections have a natural stratification induced by a \(C^*\)-action. In both of these stratifications, each stratum is a holomorphic fibration over a connected component of complex variations of Hodge structure. While the nonabelian Hodge correspondence provides a homeomorphism between Higgs bundles and flat connections, this...   More >

Seminar 211, Economic History: When Did Growth Begin? New Estimates of Productivity Growth in England from 1250 to 1860

Seminar | April 29 | 2-3:30 p.m. | 639 Evans Hall

 Jón Steinsson, University of California - Berkeley

 Department of Economics

Probabilistic Operator Algebra Seminar: On minimal and unbounded topologies

Seminar | April 29 | 2-4 p.m. | 736 Evans Hall

 Mitchell Taylor, UC Berkeley

 Department of Mathematics

In this talk I will discuss the process of “unbounding” a topology on a vector lattice. In the $L_p$-space case this process converts the norm topology to the topology of convergence in measure . I will then discuss how unbounded topologies connect with the minimal and universal objects in the category of vector lattices, and how some of their natural properties cannot be characterized in ZFC.

Arithmetic Geometry and Number Theory RTG Seminar: Lifting irreducible Galois representations

Seminar | April 29 | 3-5 p.m. | 748 Evans Hall

 Stefan Patrikis, University of Utah

 Department of Mathematics

A basic question in the study of Galols representations is whether a mod p representation, valued in any reductive group, of the absolute Galois group of a number field admits a geometric p-adic lift. In some cases this question has a positive answer, in other cases a negative answer, and sometimes we simply don't know what to expect. Perhaps the most general setting in which one can hope for a...   More >

New Discoveries in East and Southeast Asian Archaeology

Differential Geometry Seminar: Non-Archimedean aspects of the space of Kähler metrics

Seminar | April 29 | 3:10-4 p.m. | 939 Evans Hall

 Mattias Jonsson, University of Michigan

 Department of Mathematics

Let (X,L) be a polarized complex manifold. A good understanding of the space of Kähler metrics in the cohomology class of L is crucial to variational approach to constructing canonical metrics on X. I will discuss joint work with S. Boucksom, in which we analyze geodesic rays in (the completion of) this space, partially from a non-Archimedean point of view.

Analysis and PDE Seminar: Resonances on asymptotically flat black holes

Seminar | April 29 | 4:10-5 p.m. | 740 Evans Hall

 Dejan Gajic, University of Cambridge

 Department of Mathematics

A fundamental problem in the context of Einstein’s equations of general relativity is to understand the dynamical evolution of small perturbations of stationary black hole solutions. It is expected that there is a discrete set of characteristic frequencies that play a dominant role at late times and carry information about the nature of the black hole, much like how the normal frequencies of a...   More >
