Title of Seminar: Algebraic Geometry Preprint Seminar 2025
Title of Talk: Bounding Crystalline Torsion From \'{E}tale Torsion
Speaker: Rajat Kumar Mishra, TIFR, Mumbai
Date: September 16, 2025
Time: 16:00:00 Hours
Venue: AG-77
Abstract: We explore the interplay between two torsion phenomena in smooth proper families over $p$-adic rings of integers: crystalline and \'{e}tale torsion. Following the work of Gabber and Li, we will try to see how the crystalline torsion can be controlled via the \'{e}tale torsion, the cohomological degree, and the ramification index.
