Jacobson identities for post-Lie algebras in positive characteristic

Quentin Ehret, Nicolas Gilliers

Let be a prime number. Given a restricted Lie algebra over a field of characteristic and a post-Lie operation over it, we prove the Jacobson identities for a -structure…

The Superization of Hochschild's Lemma and Restricted Lie-Rinehart Superalgebras

Sofiane Bouarroudj, Quentin Ehret, Abdenacer Makhlouf +1

The main goal of this paper is to introduce the notion of restricted Lie-Rinehart superalgebra over a field of characteristic , motivated by a generalization of Hochschild's l…

An alternative approach to deformations of restricted Lie-Rinehart algebras

Quentin Ehret

In this paper, we develop a new approach to the deformation theory of restricted Lie-Rinehart algebras in positive characteristic, based on the deformation theory of restricted mor…

Cohomology of Restricted Poisson algebras in characteristic 2

Sofiane Bouarroudj, Quentin Ehret, Jiefeng Liu

In this paper, we study restricted Poisson algebras in characteristic 2 and their relationship with restricted Lie-Rinehart algebras, for which we develop a cohomology theory and i…

Cohomology and deformations of restricted Lie algebras and their morphisms in positive characteristic

Quentin Ehret, Abdenacer Makhlouf

The main purpose of this paper is to study cohomology and develop a deformation theory of restricted Lie algebras in positive characteristic . In the case , it is show…
