We introduce a notion of Koszul A-algebra that generalizes Priddy's notion of a Koszul algebra and we use it to construct small A-algebra models for Hochschild cochains. As an application, this yields new techniques for computing free loop space homology algebras of manifolds that are either formal or coformal (over a field or over the integers). We illustrate these techniques in two examples.

Koszul A∞-代数和自由环空间同调

我们引入了 Koszul 的概念一种- 概括了 Priddy 的 Koszul 代数概念的代数,我们用它来构造小的一种- Hochschild cochains 的代数模型。作为一个应用程序,这产生了用于计算流形的自由环空间同调代数的新技术,这些流形要么是形式的,要么是共形式的(在域上或整数上)。我们用两个例子来说明这些技术。
