相对Rota-Baxter李代数的表示、上同调及其应用

Representations and cohomologies of relative Rota-Baxter Lie algebras and applications

Jun Jiang, Yunhe Sheng

摘要:

本文首先给出了相对Rota-Baxter李代数的表示的概念,并引入了系数在表示中的相对Rota-Baxter李代数的上同调.然后利用第二上同调群对相对Rota-Baxter李代数的交换扩张进行了分类,并利用第三上同调群对骨架相对Rota-Baxter李2-代数进行了分类.最后,利用所建立的相对Rota-Baxter李代数的表示和上同调的一般框架,给出了Rota-Baxter李代数的表示的概念,它与文献中Rota-Baxter结合代数的表示是一致的,并引入了系数在表示中的Rota-Baxter李代数的上同调.应用于Rota-Baxter李代数和骨架Rota-Baxter李2-代数的交换扩张的分类。

英文摘要:

In this paper, first we give the notion of a representation of a relative Rota-Baxter Lie algebra and introduce the cohomologies of a relative Rota-Baxter Lie algebra with coefficients in a representation. Then we classify abelian extensions of relative Rota-Baxter Lie algebras using the second cohomology group, and classify skeletal relative Rota-Baxter Lie 2-algebras using the third cohomology group as applications. At last, using the established general framework of representations and cohomologies of relative Rota-Baxter Lie algebras, we give the notion of representations of Rota-Baxter Lie algebras, which is consistent with representations of Rota-Baxter associative algebras in the literature, and introduce the cohomologies of Rota-Baxter Lie algebras with coefficients in a representation. Applications are also given to classify abelian extensions of Rota-Baxter Lie algebras and skeletal Rota-Baxter Lie 2-algebras.
