Title of Seminar: Algebraic Geometry Preprint Seminar 2025
Title of Talk: Castelnuovo-Mumford Regualarity over Scrolls and Splitting Criteria
Speaker: Debojyoti Bhattacharya, TIFR, Mumbai
Date: April 21, 2025
Time: 16:00:00 Hours
Venue: AG-77

Abstract: In this talk, we will discuss the recently introduced notion of Castelnuovo-Mumford regularity suit- able for scrolls obtained as projectivisations of direct sums of line bundles on P^m and Horrocks type splitting criteria for vector bundles. This is based on the preprint https://arxiv.org/abs/2501.06361 by F. Malaspina and G.K. Sankaran.
