关于结合型三元代数的上同调的注记

Notes on Cohomologies of Ternary Algebras of Associative Type

H. Ataguema, A. Makhlouf

摘要:

本文研究结合型三元代数的上同调。特别研究了部分结合三代数和弱全结合三代数的情形。此外,我们考虑了Takhtajan的构造,它是利用李代数的Chevalley-Eilenberg上同调构造三元Nambu-李代数的上同调,并在结合型三元代数的情况下讨论了它.本文的主要结果之一是部分结合三代数不存在变形上同调,这意味着它们的运算不是Koszul运算。

英文摘要:

The aim of this paper is to investigate the cohomologies for ternary algebras of associative type. We study in particular the cases of partially associative ternary algebras and weak totally associative ternary algebras. Also, we consider the Takhtajan's construction, which was used to construct a cohomology of ternary Nambu-Lie algebras using Chevalley-Eilenberg cohomology of Lie algebras, and discuss it in the case of ternary algebras of associative type. One of the main results of this paper states that a deformation cohomology does not exist for partially associative ternary algebras which implies that their operad is not a Koszul operad.
