Expanders and Extractors

Workshop | January 30 – February 3, 2017 every day |  Calvin Laboratory (Simons Institute for the Theory of Computing)

 Simons Institute for the Theory of Computing

This workshop will focus on explicit constructions of graphs and functions with pseudorandom properties. There will be two main themes related to each object in the title. For expanders, these will be proofs of existence of expander graphs using lifts, a la Bilu-Linial and Marcus-Spielman-Srivastava, and the possibility of using the method to obtain explicit constructions of Ramanujan expanders...   More >

The Effect of Cumulative Advantages on the Stability and Dynamics of Collaborations in US Physics, Chemistry and Sociology from 1980 to 2015

Seminar | January 30 | 12-1 p.m. | Goldman School of Public Policy, 355 GSPP, 3rd floor,1893 LeRoy Ave

 Oliver Wieczorek, Visiting Scholar, Sociology, Bamberg, Germany; Heiko Heiberger, Postdoctoral Researcher,Department for Micro-Sociology at University of Bremen, Germany

 Center for Studies in Higher Education

In academia, effects of “cumulative advantage” are well studied in regards to different types of resources. Those resources are money, influence, number of collaborations, number of publications and the impact of the findings. In other words: the rich and famous departments and researchers get richer and more famous over time while the poor get (relatively) poorer. This effect is visible on both...   More >

Combinatorics Seminar: Dyck paths and positroids from unit interval orders

Seminar | January 30 | 12:10-1 p.m. | 939 Evans Hall

 Anastasia Chavez and Felix Gotti, UC Berkeley

 Department of Mathematics

It is well known that the number of non-isomorphic unit interval orders on $[n]$ equals the $n$-th Catalan number. Using work of Skandera and Reed and work of Postnikov, we show that each unit interval order on $[n]$ naturally induces a rank $n$ positroid on $[2n]$. We call the positroids produced in this fashion unit interval positroids. We characterize the unit interval positroids by describing...   More >

String-Math Seminar: Cluster Theory of the Coherent Satake Category

Seminar | January 30 | 2-3 p.m. | 402 LeConte Hall

 Harold Williams, University of Texas

 Department of Mathematics

We discuss recent work showing that in type A_n the category of equivariant perverse coherent sheaves on the affine Grassmannian categorifies the cluster algebra associated to the BPS quiver of pure N=2 gauge theory. Physically, this can be understood as a statement about line operators in this theory, following ideas of Gaiotto-Moore-Neitzke, Costello, and Kapustin-Saulina – in short, coherent...   More >

 Vincent Poor, Princeton University

 Electrical Engineering and Computer Sciences (EECS)

Smart grid involves the imposition of an advanced cyber layer atop the physical layer of the electricity grid, in order to improve the efficiency, security and cost of electricity use and distribution, and to allow for greater decentralization of power generation and management. This cyber-physical setting motivates a number of problems in network analysis, and this talk will briefly describe...   More >

Delineating Protein Transportation Processes: Hierarchical Models for Single-Molecule Data

Seminar | January 30 | 4-5 p.m. | 1011 Evans Hall

 Yang Chen, Department of Statistics, Harvard University

 Department of Statistics

Single-molecule experiments investigate the kinetics of individual molecules and thus can substantially enhance our understandings of various organisms. Analyzing data from single-molecule experiments poses a number of challenges: (a) the inherent stochasticity of molecules is usually buried in random experimental noise; (b) single-molecule behavior can be highly volatile. For both of these...   More >

Commutative Algebra and Algebraic Geometry: The Eisenbud-Goto Regularity Conjecture

Seminar | January 30 | 4:10-5 p.m. | 939 Evans Hall

 Irena Peeva, Cornell University

 Department of Mathematics

Regularity is a numerical invariant that measures the complexity of the structure of homogeneous ideals in a polynomial ring. Papers of Bayer-Mumford and others give examples of families of ideals attaining doubly exponential regularity. In contrast, Bertram-Ein-Lazarsfeld, Chardin-Ulrich, and Mumford have proven that there are nice bounds on the regularity of the ideals of smooth (or nearly...   More >

Seminar | January 30 | 4:15-5 p.m. | LeConte Hall, Lecture Hall 1

 Wim Leemans, Director, Accelerator Technology and Applied Physics Division, LBNL

 Department of Physics

We will discuss the progress on building laser powered, plasma based particle accelerators where electrons surf on waves and can reach energy levels in a few inches that, if one relies on conventional methods, would require machines multiple football fields long. Although many challenges remain, this new technology is at the brink of offering a profoundly different way in which we may build...   More >

What is history? or, the life and times of water hyacinth: 2017 Anthropology Distinguished Lecture

Special Event | January 30 | 5-7 p.m. | Doe Library, Morrison Room

 Anna L. Tsing, UCSC

 Department of Anthropology

Debates about the meaning and role of “history” in anthropology have characterized the discipline since its inception. This lecture revisits some of these debates to consider how anthropologists might better incorporate the contingent and transformative abilities of other species into our stories of what happened. Can “history” make room for multiple ontologies? To show how articulations across...   More >
