Two-part lecture series: Rational approximations and Subspace Theorem | Some applications of Subspace Theorem

APRIL 10, 2022

It gives us immense pleasure to announce our next speaker in the ‘Two-part Lecture Series’, jointly hosted by CMIT and the School of Mathematics, IISER Thiruvananthapuram.

Kindly note that the two-part lectures will be delivered in a manner to cover the necessary basics in the first part of the talk, while the second part builds upon the same and continues.

The following two-part lecture will be delivered by Prof R. Thangadurai, Harish Chandra Research Institute, on April 11 and 13, 2022, at 11:30 AM.

Speaker: Dr. Saikat Chatterjee, SoM, IISER Thiruvananthapuram

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
