Varieties of elementary subalgebras of maximal dimension for modular Lie algebras (1503.01043v1)
Published 3 Mar 2015 in math.RT and math.AG
Abstract: Motivated by questions in modular representation theory, Carlson, Friedlander, and the first author introduced the varieties E(r, g) of r-dimensional abelian p-nilpotent subalgebras of a p-restricted Lie algebra g. In this paper, we identify the varieties E(r, g) for a reductive restricted Lie algebra g and r the maximal dimension of an abelian p-nilpotent subalgebra of g.
