Cohomology of twisted polynomial superfunctors through the twisting spectral sequence

Algebraic Topology 2026-01-28 v1

Abstract

We want to compute generic Ext\mathrm{Ext}-spaces of twisted polynomial functors in relation to the Ext\mathrm{Ext}-spaces of the untwisted ones, modulo a parametrisation. Thanks to the study of a spectral sequence we get to a computation in low degrees, with remarkable consequences at the level of generic cohomology.
