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…

Rota-Baxter operators on $I ¨ $ -Lie algebras

Yin Chen, Shan Ren, Jiawen Shan +1

This article explores Rota-Baxter operators on finite-dimensional $I ¨ $ -Lie algebras over a field of characteristic not 2. We provide several methods for constructing left-symmetric…
