相容结合代数的(余)同调

(Co)homology of compatible associative algebras

Taoufik Chtioui, Apurba Das, Sami Mabrouk

摘要:

本文定义并研究相容结合代数$A$的(上)同调论。首先,我们构造了一个新的分次李代数,其Maurer-Cartan元由相容结合结构给出.然后定义了相容结合代数$A$的上同调,作为应用,研究了$A$的扩张、变形和有穷级变形的扩张性.最后,我们考虑相容预单向量空间和相容结合代数的同调性。

英文摘要:

In this paper, we define and study (co)homology theories of a compatible associative algebra $A$. At first, we construct a new graded Lie algebra whose Maurer-Cartan elements are given by compatible associative structures. Then we define the cohomology of a compatible associative algebra $A$ and as applications, we study extensions, deformations and extensibility of finite order deformations of $A$. We end this paper by considering compatible presimplicial vector spaces and the homology of compatible associative algebras.
