Classification of 5-dimensional restricted Lie algebras over perfect fields, I

Iren Darijani, Hamid Usefi

The purpose of this paper is to classify all $p$ -nilpotent restricted Lie algebras of dimension 5 over perfect fields of characteristic $p \geq 5$ . Our work builds upon the recent w…

Isomorphism invariants of enveloping algebras

Hamid Usefi

Let $L$ be a Lie algebra with its enveloping algebra $U (L)$ over a field. In this paper we survey results concerning the isomorphism problem for enveloping algebras: given another…

Restricted enveloping algebras whose skew and symmetric elements are Lie metabelian

Salvatore Siciliano, Hamid Usefi

Let $L$ be a restricted Lie algebra over a field of characteristic $p > 2$ and denote by $u (L)$ its restricted enveloping algebra. We establish when the symmetric or skew elements of…

The classification of p-nilpotent restricted Lie algebras of dimension at most 4

Csaba Schneider, Hamid Usefi

In this paper we obtain the classification of $p$ -nilpotent restricted Lie algebras of dimension at most four over a perfect field of characteristic p.
