Nationhood in Antiquity. Was There Any Such Thing?: A History Department Colloquium

Colloquium | February 25 | 12-2 p.m. | 3335 Dwinelle Hall

 Erich Gruen, Wood Professor Emeritus, UC Berkeley Department of History

 Department of History

Did the idea of nationhood have any significance in the ancient world? Or is it simply the importation and imposition of a concept framed in the modern world? Wherein lay the focal point of allegiance or the sense of collective identity in ancient societies? Is the notion of nation an anachronism, even a deception, when applied to antiquity? The talk does not profess to resolve this large and...   More >

Combinatorics Seminar: Characterization of queer supercrystals

Seminar | February 25 | 12:10-1 p.m. | 939 Evans Hall

 Wencin Poh, UC Davis

 Department of Mathematics

We provide a characterization of the crystal bases for the quantum queer superalgebra recently introduced by Grantcharov et al.. This characterization is a combination of local queer axioms generalizing Stembridge's local axioms for crystal bases for simply-laced root systems, which were recently introduced by Assaf and Oguz, with further axioms and a new graph $G$ characterizing the relations of...   More >

What accounts for socioeconomic differences in child-directed speech? The role of resource scarcity

Colloquium | February 25 | 12:10-1:15 p.m. | 1102 Berkeley Way West

 Monica Ellwood-Lowe, Department of Psychology

 Department of Psychology

Parents with fewer educational and economic resources (low socioeconomic-status, SES) tend to speak less with their children, with important consequences for children’s later language outcomes and, ultimately, their performance in school. Despite this well-established link, surprisingly little research has focused on why such a gap exists. In fact, most researchers rely on individual-level...   More >

String-Math Seminar: Higher Airy structures, W-algebras and topological recursion

Seminar | February 25 | 2-3 p.m. | 402 LeConte Hall

 Vincent Bouchard, University of Alberta

 Department of Mathematics

Virasoro constraints are omnipresent in enumerative geometry. Recently, Kontsevich and Soibelman introduced a generalization of Virasoro constraints in the form of Airy structures. It can also be understood as an abstract framework underlying the topological recursion of Chekhov, Eynard and Orantin. In this talk I will explain how the triumvirate of Virasoro constraints, Airy structures and...   More >

Probabilistic Operator Algebra Seminar: Phase transitions for random quantum states

Seminar | February 25 | 2-4 p.m. | 736 Evans Hall

 Stanislaw J. Szarek, Case Western Reserve University and Sorbonne University Paris

 Department of Mathematics

Consider a quantum system consisting of N particles, and assume that it is in a random pure state (i.e., uniform over the sphere of the corresponding Hilbert space H). Let A and B be two subsystems consisting of k particles each. Then there exists a threshold value $k_0 \sim N/5$ such that

(i) if $k > k_0$, then A and B typically share entanglement

(ii) if $k < k_0$, then A and B typically do...   More >

Arithmetic Geometry and Number Theory RTG Seminar: The Breuil-Mezard conjecture for potentially crystalline deformation rings

Seminar | February 25 | 3-5 p.m. | 748 Evans Hall

 Brandon Levin, University of Arizona

 Department of Mathematics

The Breuil-Mezard conjecture predicts the geometry of local Galois deformation rings with p-adic Hodge theory condition in terms of modular representation theory. I will begin by reformulating this conjecture in terms of the Emerton-Gee moduli stack of mod p Galois representations. I will then describe joint work in progress with Daniel Le, Bao V. Le Hung, and Stefano Morra where we prove the...   More >

Privately Learning High-Dimensional Distributions: BLISS Seminar

Seminar | February 25 | 3-4 p.m. | 540 Cory Hall

 Gautam Kamath, Simons

 Electrical Engineering and Computer Sciences (EECS)

We present novel, computationally efficient, and differentially private algorithms for two fundamental high-dimensional learning problems: learning a multivariate Gaussian in R^d and learning a product distribution in {0,1}^d in total variation distance. The sample complexity of our algorithms nearly matches the sample complexity of the optimal non-private learners for these tasks in a wide range...   More >

Jessica Coon, "Mayan Agent Focus and the Ergative Extraction Constraint: Facts and Fictions Revisited"

Colloquium | February 25 | 3:10-5 p.m. | 370 Dwinelle Hall

 Jessica Coon, McGill University

 Department of Linguistics

Many languages of the Mayan family restrict the extraction of transitive (ergative) subjects for focus, wh-questions, and relativization (A’-extraction). We follow Aissen (2017) in labelling this restriction the ergative extraction constraint (EEC). In this talk, we offer a unified account of the EEC within Mayan languages, as well as an analysis of the special construction known as Agent Focus...   More >

Differential Geometry Seminar: Eguchi-Hanson singularities in U(2)-invariant Ricci flow

Seminar | February 25 | 3:10-4 p.m. | 939 Evans Hall

 Alexander Appleton, UC Berkeley

 Department of Mathematics

We show that a Ricci flow in four dimensions can develop singularities modeled on the Eguchi-Hanson space. In particular, we prove that starting from a class of asymptotically cylindrical $U(2)$-invariant initial metrics on $TS^2$, a Type II singularity modeled on the Eguchi-Hanson space develops in finite time. Furthermore we show that in our setup blow-up limits at larger scales are isometric...   More >

What do language disorders reveal about the brain? From classic models to network approaches

Colloquium | February 25 | 3:30-5 p.m. | 1104 Berkeley Way West

 Nina Dronkers, Psychology

 Department of Psychology

Past approaches to the study of language and the brain have focused largely on the contributions of Broca's and Wernicke's areas. By using advanced neuroimaging techniques with individuals who have aphasia, we have now learned that language is an extraordinarily complex system that requires an extensive and interactive network of brain regions to sustain it. We have also learned that an intricate...   More >

American Sutra: Buddhism and the Incarceration of Japanese Americans during WWII

Colloquium | February 25 | 4-6 p.m. | 180 Doe Library

 Center for Japanese Studies (CJS), Asian American Studies, Department of Ethnic Studies, Center for Buddhist Studies, Berkeley Center for the Study of Religion

Duncan Ryūken Williams (USC) will discuss his new book “American Sutra” about Buddhism and the WWII Japanese American internment. The fact that the vast majority of Japanese Americans were Buddhist was responsible for why nearly 120,000 persons of Japanese ancestry, two-third of whom were American citizens, were targeted for forcible removal from the Pacific coast states and incarcerated in...   More >

Seminar | February 25 | 4:10-5:30 p.m. |  Evans Hall

 Olivier Tercieux, Paris School of Economics

 Department of Economics

To assign teachers to schools, a modified version of the well-known deferred accep-tance mechanism has been proposed in the literature and is used in practice. We showthat this mechanism fails to be fair and efficient for both teachers and schools. Weidentify a class of strategy-proof mechanisms that cannot be improved upon in terms ofboth efficiency and fairness. We show that these mechanisms...   More >

In and out of the Body and into the Machine with Chico MacMurtrie

Presentation | February 25 | 6:30 p.m. |  Berkeley Art Museum and Pacific Film Archive

 Berkeley Art Museum and Pacific Film Archive

Chico MacMurtrie’s work pushes the boundaries between robotic sculpture, new media installation, and performance. Immersed in the Bay Area’s art and technology counterculture of the 1990s, he became known for his anthropomorphic, computer-controlled sculptures, which evolved over the years into a “society of machines.” Today, operating out of his studio in Brooklyn, also known as the “Robotic...   More >
