CMSA Active Matter: Control of actin cable length by decelerated growth and network geometry
SEMINARS, CMSA EVENTS
April 13, 2023 1:00 pmSpeaker: Shane McInally - Brandeis University
The sizes of many subcellular structures are coordinated with cell size to ensure that these structures meet the functional demands of the cell. In eukaryotic cells, these subcellular structures are...

MIT-Harvard-MSR Combinatorics Seminar: Vector bundles, valuations, tropical linear spaces and matriods
SEMINARS, HARVARD-MIT COMBINATORICS
April 12, 2023 4:15 pmSpeaker: Kiumars Kaveh - University of Pittsburgh
Torus equivariant rank r vector bundles on a toric variety (toric vector bundles) were famously classified by Klyachko (1989) using certain combinatorial data of compatible filtrations in an r-dimensional vector...

CMSA Probability Seminar: Large deviations of Selberg’s central limit theorem
SEMINARS, CMSA EVENTS
April 12, 2023 3:30 pmSpeaker: Emma Bailey - CUNY
Selberg’s CLT concerns the typical behaviour of the Riemann zeta function and shows that the random variable $\Re \log \zeta(1/2 + i t)$, for a uniformly drawn $t$, behaves as...

Number Theory Seminar: Square root p-adic L-functions
SEMINARS, NUMBER THEORY
April 12, 2023 3:00 pmSpeaker: Michael Harris - Columbia
The Ichino–Ikeda conjecture, and its generalization to unitary groups by N. Harris, gives explicit formulas for central critical values of a large class of Rankin–Selberg tensor products. The version for...

CMSA Colloquium: Unexpected Uses of Neural Networks: Field Theory and Metric Flows
SEMINARS, CMSA EVENTS
April 12, 2023 12:30 pmSpeaker: James Halverson - Northeastern University
We are now quite used to the idea that deep neural networks may be trained in a variety of ways to tackle cutting-edge problems in physics and mathematics, sometimes leading...

Harvard–MIT Algebraic Geometry Seminar: Mirror symmetry, stability conditions, and geometric invariant theory
SEMINARS, HARVARD-MIT ALGEBRAIC GEOMETRY
April 11, 2023 3:00 pmSpeaker: Tristan Collins - MIT
Bridgeland stability conditions were originally motivated by the concept of Pi stability in theoretical physics, as introduced in work of M. Douglas. Pi stability is an attempt to describe BPS...

CMSA Probability Seminar: Localization for random band matrices
SEMINARS, CMSA EVENTS
April 10, 2023 3:00 pmSpeaker: Ron Peled - Tel Aviv University
**Note unusual day and time** I will explain an approach via "an adaptive Mermin-Wagner style shift" which proves localization of N x N Gaussian random band matrices with band width...

CMSA Swampland Seminar: Swampland bounds on the abelian gauge sectors
SEMINARS, CMSA EVENTS
April 10, 2023 11:00 amSpeaker: Seung-Joo Lee - IBS Daejeon
In this talk we will derive various bounds on the 0-form and the 1-form abelian gauge sectors of gravitational effective theories in 6 dimensions with minimal supersymmetry. We will start...

Gauge Theory and Topology Seminar: Instantons on Joyce’s G2-manifolds
Gauge Theory and Topology Seminar, SEMINARS
April 7, 2023 3:30 pmSpeaker: Langte Ma - Stony Brook University
As 7-manifolds with special holonomy, examples of compact G2-manifolds were first constructed by Joyce as resolutions of flat G2-orbifolds. Later Walpuski constructed non-trivial G2-instantons over Joyce’s manifolds via gluing techniques. In this...
