Abelian supplements in almost simple groups
Mauro Costantini, Andrea Lucchini, Daniele Nemmi
Let be a finite almost simple group with socle . In this paper we prove that whenever is abelian, then there exists an abelian subgroup of such that $G=AG_…
Spherical birational sheets in reductive groups
Filippo Ambrosio, Mauro Costantini
We classify the spherical birational sheets in a complex simple simply-connected algebraic group. We use the classification to show that, when is a connected reductive complex…
Finite-dimensional pointed Hopf algebras over finite simple groups of Lie type VI. Suzuki and Ree groups
Giovanna Carnovale, Mauro Costantini
We analyse the rack structure of conjugacy classes in simple Suzuki and Ree groups and determine which classes are kthulhu. Combining this results with abelian rack techniques, we…
Local automorphisms of finite dimensional simple Lie algebras
Mauro Costantini
Let be a finite dimensional simple Lie algebra over an algebraically closed field of characteristic . A linear map is call…
A classification of spherical conjugacy classes
Mauro Costantini
Let G be a simple algebraic group over an algebraically closed field k. We classify the spherical conjugacy classes of G.
On Lusztig's map for spherical unipotent conjugacy classes
Giovanna Carnovale, Mauro Costantini
We provide an alternative description of the restriction to spherical unipotent conjugacy classes, of Lusztig's map Psi from the set of unipotent conjugacy classes in a connected r…
