Hom-Leibniz-Rinehart代数的上同调与交叉模扩张

Cohomology and crossed modules extension of Hom-Leibniz-Rinehart algebras

Yanhui Bi, Danlu Chen, Tao Zhang

摘要:

本文引入了Hom-Leibniz-Rinehart代数的交叉模的概念。研究了Hom-Leibniz-Rinehart代数的上同调和扩张理论。证明了Hom-Leibniz-Rinehart代数的交换扩张的等价类与第二上同调群的元素之间存在一一对应.进一步证明了存在从Hom-Leibniz-Rinehart代数的$α$ -交叉模扩张到Hom-Leibniz-Rinehart代数的第三上同调群的自然映射.

英文摘要:

In this paper, we introduce the concept of crossed module for Hom-Leibniz-Rinehart algebras. We study the cohomology and extension theory of Hom-Leibniz-Rinehart algebras. It is proved that there is one-to-one correspondence between equivalence classes of abelian extensions of Hom-Leibniz-Rinehart algebras and the elements of second cohomology group. Furthermore, we prove that there is a natural map from $α$-crossed modules extension of Hom-Leibniz-Rinehart algebras to the third cohomology group of Hom-Leibniz-Rinehart algebras.
