MIT-Harvard-MSR Combinatorics Seminar: Realizable Standard Young Tableaux
SEMINARS, HARVARD-MIT COMBINATORICS
April 5, 2023 4:15 pmSpeaker: Amanda Burcroff - Harvard
We will discuss enumerative and structural properties of two families of standard Young tableaux, the realizable rectangular tableaux and the realizable staircase tableaux. The realizable rectangular tableaux come from tropical...

CMSA Probability Seminar: Sampling from the SK and mixed p-spin measures with stochastic localization
SEMINARS, CMSA EVENTS
April 5, 2023 3:30 pmSpeaker: Ahmed El Alaoui - Cornell
I will present an algorithm which efficiently samples from the Sherrington-Kirkpatrick (SK) measure with no external field at high temperature. The approach is based on the stochastic localization process of...

Number Theory Seminar: Evaluating the wild Brauer group
SEMINARS, NUMBER THEORY
April 5, 2023 3:00 pmSpeaker: Rachel Newton - King's College London
The local global approach to the study of rational points over number fields begins by embedding the set of rational points on a variety X into the set of its...

Mathematical Picture Language Seminar: The TTbar deformation of 2d quantum field theory and modular forms
MATHEMATICAL PICTURE LANGUAGE, SEMINARS
April 4, 2023 9:30 amSpeaker: John Cardy - UC Berkeley and All Souls College, Oxford
"TTbar" deformed 2d quantum field theory is a non-local theory in which Minkowski space is deformed in a state-dependent but consistent manner. For a massive theory this is equivalent to...

Introductory Mathematics Seminar: Framing and Implementing Organizational Change in University Entry-Level Mathematics
SEMINARS
April 4, 2023 4:30 pmSpeaker: Deborah Moore-Russo - University of Oklahoma
Finding, applying and learning from the appropriate frameworks to use as lenses for educational research is an important task. In this talk I will share the three theoretical frameworks that...

Harvard–MIT Algebraic Geometry Seminar: Resonance and Koszul modules in algebraic geometry
SEMINARS, HARVARD-MIT ALGEBRAIC GEOMETRY
April 4, 2023 3:00 pmSpeaker: Gavril Farkas - Humboldt University
Inspired from ideas in topology, Koszul modules and the associated resonance varieties turned out to have important algebro-geometric applications for instance to (i) Green's Conjecture on syzygies of canonical curves,...

CMSA Colloquium: Black hole microstate counting from the gravitational path integral
SEMINARS, CMSA EVENTS
April 3, 2023 11:00 amSpeaker: Luca Iliesiu - Stanford University
Reproducing the integer count of black hole micro-states from the gravitational path integral is an important problem in quantum gravity. In the first part of the talk, I will show that, by...

CMSA Algebraic Geometry in String Theory: Kähler–Einstein metrics on families of Fano varieties
SEMINARS, CMSA EVENTS
April 3, 2023 10:00 amSpeaker: Chung-Ming Pan - Institut de Mathématiques de Toulouse
This talk aims to introduce a pluripotential approach to study uniform a priori estimates of Kähler--Einstein (KE) metrics on families of Fano varieties. I will first recall basic tools in...
