一个BiHom结合代数是一个(非结合)代数A,它具有两个可交换的乘法线性映射α,β:A → A,使得对任意的a,B,c ∈ A,α(a)(bc)=(ab)β(c).这一概念出现在研究代数在所谓的组Hom-categories。在本文中,我们引入了BiHom-李代数(也是用范畴方法)和BiHom-双代数。我们通过给出一些基本性质和构造(表示、扭曲张量积、粉碎积等)来讨论这些新结构。
A BiHom-associative algebra is a (nonassociative) algebra A endowed with two commuting multiplicative linear maps α,β : A → A such that α(a)(bc) = (ab)β(c), for all a,b,c ∈ A. This concept arose in the study of algebras in so-called group Hom-categories. In this paper, we introduce as well BiHom-Lie algebras (also by using the categorical approach) and BiHom-bialgebras. We discuss these new structures by presenting some basic properties and constructions (representations, twisted tensor products, smash products etc).
