非交换形式蕴涵着交换形式和李形式

Non-commutative formality implies commutative and Lie formality

Bashar Saleh

摘要:

在一个领域的特征零,我们证明了两个形式条件。证明了一个dg李代数是形式的当且仅当它的泛包络代数是形式的。我们还证明了交换dg代数是形式dg结合代数当且仅当它是形式dg代数。我们提出了这些定理在有理同伦理论的一些后果。

英文摘要:

Over a field of characteristic zero we prove two formality conditions. We prove that a dg Lie algebra is formal if and only if its universal enveloping algebra is formal. We also prove that a commutative dg algebra is formal as a dg associative algebra if and only if it is formal as a commutative dg algebra. We present some consequences of these theorems in rational homotopy theory.
