Let G be a quasi simple algebraic group over an algebraically closed field k whose characteristic is not very bad for G, and let B be a Borel subgroup of G with Lie algebra b. Given a B-stable abelian subalgebra a of [b, b], we parametrize the B-orbits in a and we describe their closure relations.

Abstract
Let G be a quasi simple algebraic group over an algebraically closed field k whose characteristic is not very bad for G, and let B be a Borel subgroup of G with Lie algebra b. Given a B-stable abelian subalgebra a of [b, b], we parametrize the B-orbits in a and we describe their closure relations.File in questo prodotto:
