张量积的李结构纲要

A compendium of Lie structures on tensor products

Pasha Zusmanovich

摘要:

我们演示了如何使用一个简单的线性代数技术计算当前李代数的低次上同调,可以用来计算其他类型的结构,这样的李代数,并讨论进一步的推广,应用和相关问题。在这样做的同时,我们触及这样的看似不同的主题,结合代数的无限表示型,Hom-Lie结构,泊松括号的流体动力型,Novikov代数,简单的李代数的小特征,和Koszul对偶运算。

英文摘要:

We demonstrate how a simple linear-algebraic technique used earlier to compute low-degree cohomology of current Lie algebras, can be utilized to compute other kinds of structures on such Lie algebras, and discuss further generalizations, applications, and related questions. While doing so, we touch upon such seemingly diverse topics as associative algebras of infinite representation type, Hom-Lie structures, Poisson brackets of hydrodynamic type, Novikov algebras, simple Lie algebras in small characteristics, and Koszul dual operads.
