Title: On the path correspondences of quantum graphs
Time, day and date: 4:00:00 PM - 5:00:00 PM, Wednesday, August 05
Venue: Ramanujan Hall
Abstract: In this talk we will describe a theory of paths for quantum graphs. In the spirit of the edge correspondence of Brannan–Hamidi–Ismert–Nelson–Wasilewski, we associate to each quantum graph a sequence of path correspondences modelling its quantum paths of every length. These assemble into a subproduct system over the centre of the underlying vertex algebra, and I will illustrate the construction on classical, complete, and trivial quantum graphs. This is based on a joint work in progress with Sourav Khatua.
