Title of Seminar: Algebraic Geometry Preprint Seminar 2025
Title of Talk: Geometry and arithmetic of geometrically integral regular del Pezzo surfaces
Speaker: Sudipta Das, TIFR, Mumbai
Date: October 14, 2025
Time: 16:00:00 Hours
Venue: AG-77
Abstract: In this talk, our primary objective will be to classify geometrically integral regular del Pezzo surfaces that are not geometrically normal over imperfect fields. Utilizing this classification, we will explore a condition that ensures these surfaces are rational. This talk is based on a research article by Fabio Bernasconi and Hiromu Tanaka.
