Hom-结合代数和协变Hom-双代数上的Rota-Baxter系统

Rota-Baxter systems on Hom-associative algebras and covariant Hom-bialgebras

Apurba Das

摘要:

Rota-Baxter系统是由Brzezienski引入的,它是Rota-Baxter算子的推广,与树状结构、结合Yang-Baxter对和协变双代数有关。本文定义了Hom-结合代数上的Rota-Baxter系统,并证明了它们如何在基础Hom-结合代数上诱导出Hom-树状结构和弱伪扭子.本文引入了Hom-Yang-Baxter偶和协变Hom-bialgebra的概念。给定一个Hom-Yang-Baxter对,我们构造了一个扭Rota-Baxter系统和一个(拟三角)协变Hom-bialgebra.最后,我们考虑了协变Hom-双代数上的余积的扰动。

英文摘要:

Rota-Baxter systems were introduced by Brzeziński as a generalization of Rota-Baxter operators that are related to dendriform structures, associative Yang-Baxter pairs and covariant bialgebras. In this paper, we define Rota-Baxter systems on Hom-associative algebras and show how they induce Hom-dendriform structures and weak pseudotwistors on the underlying Hom-associative algebra. We introduce Hom-Yang-Baxter pairs and a notion of covariant Hom-bialgebra. Given a Hom-Yang-Baxter pair, we construct a twisted Rota-Baxter system and a (quasitriangular) covariant Hom-bialgebra. Finally, we consider perturbations of the coproduct in a covariant Hom-bialgebra.
