Ext-groups in the Category of Strict Polynomial Functors

Algebraic Topology 2023-06-22 v1

Abstract

The aim of this paper is to study, by using the mathematical tools developed by Chalupnik, Touze, and Van der Kallen, the effect of the Frobenius twist on Ext-group in the category of strict polynomial functors. As an application, we obtain explicit formulas of cohomology of the orthogonal groups and symplectic ones.
