Linkage principle for ortho-symplectic supergroups

Representation Theory 2016-08-05 v1

Abstract

The purpose of the paper is to derive linkage principle for modular representations of ortho-symplectic supergroups. We follow the approach of Doty and investigate in detail the representation theory of the orthosymplectic group OSP(21)OSP(2|1) and that of its Frobenius thickening. Using the description of flags and adjacent Borel supersubgroups we derive first the strong linkage for the Frobenius thickening GrTG_rT of the orthosymplectic supergroup GG of type SpO(2m2n+1)SpO(2m|2n+1) and SpO(2m2n)SpO(2m|2n). Based on this, we derive the linkage principle for orthosymplectic supergroup SpO(2m2n+1)SpO(2m|2n+1) and SpO(2m2n)SpO(2m|2n).
