Cohomology of twisted polynomial superfunctors through the twisting spectral sequence (2212.07970v1)
Published 15 Dec 2022 in math.AT
Abstract: We want to compute generic $\mathrm{Ext}$-spaces of twisted polynomial functors in relation to the $\mathrm{Ext}$-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.
