On localizing subcategories of Lie superalgebra representations

Representation Theory 2025-03-19 v1

Abstract

We state and prove a stratification result that allows us to classify the tensor ideal localizing subcategories for the stable module category Stab(C(g,g0ˉ))\text{Stab}(\mathcal{C}_{(\mathfrak{g}, \mathfrak{g}_{\bar 0})}) of Lie superalgbera representations which are semisimple as representations of g0ˉ\mathfrak{g}_{\bar 0} under the hypotheses that g\mathfrak{g} is a classical Lie superalgebra with a splitting detecting subalgebra zg\mathfrak{z} \leq \mathfrak{g}, as well as a natural hypothesis on realization of supports. This extends the work of the author and Nakano where a similar classification was obtained for the stable category of modules over a detecting subalgebra employing stratification in the sense of Benson, Iyengar, and Krause. Our new result involves making use of a more general stratification framework in weakly Noetherian contexts developed by Barthel, Heard, and Sanders using the Balmer-Favi notion of support for big objects in tensor triangulated categories, as well as the recently developed homological stratification of Barthel, Heard, Sanders, and Zou in using the homological spectrum.
