Title: The infinite path space of a quantum graph
Abstract: In a 2022 article, Brannan, Eifler, Voigt, and Weber defined an equivalent notion of a quantum graph via a {\em quantum adjacency matrix} on a finite-dimensional {\em quantum set}. As a quantum analogue of a Schur idempotent matrix, a quantum graph’s quantum adjacency matrix serves as a jumping off point to generalize the Cuntz—Krieger algebra arising from a classical {0,1}-matrix. The four authors also introduced two quantum Cuntz—Krieger relations on a non-commutative finite-dimensional C*-algebra which generalize the respective Cuntz—Krieger relations defined on a commutative finite-dimensional C*-algebra.
The Foias Lectures
Time: 4:00PM - 5:00PM
Location: Blocker 117
Speaker: Igor Kukavica, University of Southern California
Title: On the inviscid limit for the Navier-Stokes equations - Foias Lecture II
Abstract: The convergence of solutions of the Navier-Stokes equations to those of the Euler equations as viscosity approaches zero is a significant topic in fluid dynamics. We will review the available results, applications, and open problems in the field.
