12/9/21 Interdisciplinary Science Seminar
Title: Numerical Higher Dimensional Geometry Abstract: In 1977, Yau proved that a Kahler manifold with zero first Chern class admits a Ricci flat metric, which is uniquely determined by certain “moduli” data. […]
On the solution space of the Ising perceptron model
Member Seminar Speaker: Changji Xu Title: On the solution space of the Ising perceptron model Abstract: Consider the discrete cube $\{-1,1\}^N$ and a random collection of half spaces which includes each […]

Speaker: Lukasz Fidkowski (U Washington) Title: Gravitational anomaly of 3 + 1 dimensional Z2 toric code with fermionic charges and ferionic loop self-statistics Abstract: Quasiparticle excitations in 3 + 1 dimensions can […]
The longest induced path in a sparse random graph
Abstract: A long-standing problem in random graph theory has been to determine asymptotically the length of a longest induced path in sparse random graphs. Independent work of Luczak and Suen from […]
The Kapustin-Rozanski-Saulina “2-category” of a holomorphic integrable system
Speaker: Constantin Teleman (UC Berkeley) Title: The Kapustin-Rozanski-Saulina “2-category” of a holomorphic integrable system Abstract: I will present a construction of the object in the title which, applied to the classical Toda […]

Low regularity ill-posedness for 3D elastic waves and for 3D ideal compressible MHD driven by shock formation
Abstract: We construct counterexamples to the local existence of low-regularity solutions to elastic wave equations and to the ideal compressible magnetohydrodynamics (MHD) system in three spatial dimensions (3D). Inspired by the […]

Title: Quadratic reciprocity from a family of adelic conformal field theories Abstract: We consider a deformation of the 2d free scalar field action by raising the Laplacian to a positive real power. […]
CONDENSED MATTER PROGRAM
The methods of topology have been applied to condensed matter physics in the study of topological phases of matter. Topological states of matter are new quantum states that can be […]
