Title: Semi-direct product of categories and a Schur’s lemma for categorical representations (Part II).

Venue and time: PSB Seminar Hall | 03:00 PM (GMT +5:30), Saturday, 23rd April, 2022.

Abstract: We develop a theory of twisted actions of categorical groups using a notion of semidirect product of categories. Turning to representations, which are actions that respect vector space structures, we establish an analog of Schur’s lemma in this context.

All are cordially invited to attend the talk. Please join us in large numbers, we hope to see you all there! For any further queries, mail us at mathsclub@iisertvm.ac.in.
