Geometry and classifications of some $ω$ -Lie algebras

Yin Chen, Shan Ren, Runxuan Zhang

Using group actions and orbit-stabilizer methods, we study the geometry of isomorphism classes of finite-dimensional $ω$ -Lie algebras over a field $K$ of characteristic $\…

Some four-dimensional orthogonal invariants

Shan Ren, Runxuan Zhang

Let $p$ be an odd prime and $F_{p}$ be the prime field of order $p$ . Consider a $2$ -dimensional orthogonal group $G$ over $F_{p}$ acting on the standard representatio…

Skew-symmetric solutions of the classical Yang-Baxter equation and $O$ -operators of Malcev algebras

Shan Ren, Runxuan Zhang

We study connections between skew-symmetric solutions of the classical Yang-Baxter equation (CYBE) and $O$ -operators of Malcev algebras. We prove that a skew-symmetric so…
