Representations and cohomology for Frobenius–Lusztig kernels

open access: yes, 2011
Let Uζ be the quantum group (Lusztig form) associated to the simple Lie algebra g, with parameter ζ specialized to an ℓ-th root of unity in a field of characteristic p>0. In this paper we study certain finite-dimensional normal Hopf subalgebras Uζ(Gr) of

An algebraic slice in the coadjoint space of the Borel and the Coxeter element

open access: yes, 2011
Let g be a complex simple Lie algebra and b a Borel subalgebra. The algebra Y of polynomial semi-invariants on the dual b⁎ of b is a polynomial algebra on rank g generators (Grothendieck and Dieudonné (1965–1967)) [16].

On the automorphisms of the Drinfel'd double of a Borel Lie subalgebra

open access: yesJournal of Algebra
Let ${\mathfrak g}$ be a complex simple Lie algebra with Borel subalgebra ${\mathfrak b}$. Consider the semidirect product $I{\mathfrak b}={\mathfrak b}\ltimes{\mathfrak b}^*$, where the dual ${\mathfrak b}^*$ of ${\mathfrak b}$, is equipped with the coadjoint action of ${\mathfrak b}$ and is considered as an abelian ideal of $I{\mathfrak b}$.
