Title: Koszul A-infinity algebras and free loop space homology,
Abstract: We introduce a notion of Koszul A-infinity algebra that generalizes Priddy's
notion of a Koszul algebra and we use it to construct small A-infinity 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.
