FFLV polytopes for odd symplectic Lie algebras

Representation Theory 2021-10-06 v2 Combinatorics

Abstract

We consider "odd symplectic Lie algebras" defined in terms of maximal rank skew-symmetric forms. We provide FFLV polytopes for these algebras and prove their standard properties. In particular, we obtain a new graded character formula and PBW bases for an analogue of irreducible representations in terms of lattice points of FFLV polytopes.
