Cohomology of a restricted Lie algebra with a restricted derivation in characteristic 2

Dan Mao, Liangyun Chen

This paper mainly studies the ResLieDer pair in characteristic 2, that is, a restricted Lie algebra with a restricted derivation. We define the restricted representation of a ResLi…

Double Extensions of Multiplicative Restricted Hom-Lie Algebras

Dan Mao, Zeyu Hao, Liangyun Chen

In this paper, we study the double extension of a restricted quadratic Hom-Lie algebra $(V, [\cdot, \cdot]_{V}, α_{V}, B_{V})$ , which is an enlargement of $V$ by means of a central ext…
