Tensor products of Leibniz bimodules and Grothendieck rings
Jörg Feldvoss, Friedrich Wagemann
In this paper we define three different notions of tensor products for Leibniz bimodules. The ``natural" tensor product of Leibniz bimodules is not always a Leibniz bimodule. In or…
Semi-simple Leibniz algebras I
Jörg Feldvoss
The goal of this paper is to describe the structure of finite-dimensional semi-simple Leibniz algebras in characteristic zero. Our main tool in this endeavor are hemi-semidirect pr…
Cohomology of solvable Leibniz algebras
Jörg Feldvoss, Friedrich Wagemann
This paper is a sequel to our article [Feldvoss-Wagemann], where we mainly considered semi-simple Leibniz algebras. It turns out that the analogue of the Hochschild-Serre spectral…
On Leibniz cohomology
Jörg Feldvoss, Friedrich Wagemann
In this paper we prove the Leibniz analogue of Whitehead's vanishing theorem for the Chevalley-Eilenberg cohomology of Lie algebras. As a consequence, we obtain the second Whitehea…
Some Problems in the Representation Theory of Simple Modular Lie Algebras
Georgia Benkart, Jörg Feldvoss
The finite-dimensional restricted simple Lie algebras of characteristic p > 5 are classical or of Cartan type. The classical algebras are analogues of the simple complex Lie algebr…
Split strongly abelian p-chief factors and first degree restricted cohomology
Jörg Feldvoss, Salvatore Siciliano, Thomas Weigel
In this paper we investigate the relation between the multiplicities of split strongly abelian p-chief factors of finite-dimensional restricted Lie algebras and first degree restri…
Split abelian chief factors and first degree cohomology for Lie algebras
Jörg Feldvoss, Salvatore Siciliano, Thomas Weigel
In this paper we investigate the relation between the multiplicities of split abelian chief factors of finite-dimensional Lie algebras and first degree cohomology. In particular, w…
Outer restricted derivations of nilpotent restricted Lie algebras
Jörg Feldvoss, Salvatore Siciliano, Thomas Weigel
In this paper we prove that every finite-dimensional nilpotent restricted Lie algebra over a field of prime characteristic has an outer restricted derivation whose square is zero u…
