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…

A note on diagonal and Hermitian surfaces

Ian Blake, V. Kumar Murty, Hamid Usefi

Aspects of the properties, enumeration and construction of points on diagonal and Hermitian surfaces have been considered extensively in the literature and are further considered h…

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.
