On hom-Lie algebras
Yunhe Sheng, Zhen Xiong
In this paper, first we show that $(\g,[\cdot,\cdot],α)$ is a hom-Lie algebra if and only if $(Λ\g^*,α^*,d)$ is an -differential graded commutative algebra. Then, we rev…

Categorification of Pre-Lie Algebras and Solutions of 2-graded Classical Yang-Baxter Equations
Yunhe Sheng
In this paper, we introduce the notion of a pre-Lie 2-algebra, which is a categorification of a pre-Lie algebra. We prove that the category of pre-Lie 2-algebras and the category o…
