内禀括号与双代数的$L_\infty$ -形变理论

Intrinsic brackets and the $L_\infty$-deformation theory of bialgebras

Martin Markl

摘要:

我们发现,存在一个李括号上的上同调的任何类型的(双)代数在操作或PROP,诱导强同伦李结构上的定义上链复形,使相关的“量子”主方程捕获变形。这特别意味着一个双代数的Gerstenhaber-Schack上同调上存在一个李括号,它扩展了Hochschild上同调上的经典内禀括号,对一个关于存在这样一个括号的老问题给出了肯定的回答。

英文摘要:

We show that there exists a Lie a bracket on the cohomology of any type of (bi)algebras over an operad or a PROP, induced by a strongly homotopy Lie structure on the defining cochain complex, such that the associated "quantum" master equation captures deformations. This in particular implies the existence of a Lie bracket on the Gerstenhaber-Schack cohomology of a bialgebra that extends the classical intrinsic bracket on the Hochschild cohomology, giving an affirmative answer to an old question about the existence of such a bracket.
