Gauge Theory and Topology: Fillable contact structures from positive surgery

Gauge Theory and Topology Seminar, SEMINARS

March 10, 2023 10:30 am

Speaker: Thomas Mark - University of Virginia

For a Legendrian knot $K$ in a closed contact 3-manifold, we describe a necessary and sufficient condition for contact $n$-surgery along $K$ to yield a weakly symplectically fillable contact manifold,...

CMSA Quantum Matter in Mathematics and Physics: Quantum entropy thermalization

SEMINARS, CMSA EVENTS

March 10, 2023 10:00 am

Speaker: Yichen Huang - Harvard University

In an isolated quantum many-body system undergoing unitary evolution, the entropy of a subsystem (smaller than half the system size) thermalizes if at long times, it is to leading order...

CMSA General Relativity: Pseudospectrum and black hole quasinormal mode instability: an ultraviolet universality conjecture

SEMINARS, CMSA EVENTS

March 9, 2023 9:30 am

Speaker: Professor Jose Luis Jaramillo - Bourgogne U.

Can we measure the ‘effective regularity’ of spacetime from the perturbation of quasi-normal mode (QNM) overtones? Black hole (BH) QNMs encode the resonant response of black holes under linear perturbations,...

CMSA Probability Seminar: On the free energy of spin glasses with multiple types

SEMINARS, CMSA EVENTS

March 9, 2023 11:00 am

Speaker: Vishesh JainJean-Christophe Mourrat - ENS Lyon

In the simplest spin-glass model, due to Sherrington and Kirkpatrick, the energy function involves interaction terms between all pairs of spins. A bipartite version of this model can be obtained...

Harvard-MIT Combinatorics Seminar: Geometry of the Chromatic Symmetric Function of Trees

SEMINARS, HARVARD-MIT COMBINATORICS

March 8, 2023 4:15 pm

Speaker: Mario Sanchez - Cornell

Stanley's chromatic symmetric function is a generalization of the chromatic polynomial of a graph that encodes coloring information for graphs. One open conjecture is that non-isomorphic trees have different chromatic...

CMSA Colloquium: Conformal symmetry, Optimization algorithms and the Critical Phenomena

SEMINARS, CMSA EVENTS

March 8, 2023 12:30 pm

Speaker: Ning Su - University of Pisa

In the phase diagram of many substances, the critical points have emergent conformal symmetry and are described by conformal field theories. Traditionally, physical quantities near the critical point can be...
