Simple linear compactifications of odd orthogonal groups

Algebraic Geometry 2018-06-26 v2 Representation Theory

Abstract

We classify the simple linear compactifications of SO(2r+1), namely those compactifications with a unique closed orbit which are obtained by taking the closure of the SO(2r+1)xSO(2r+1)-orbit of the identity in a projective space P(End(V)), where V is a finite dimensional rational SO(2r+1)-module.
