Homotopy Inner Products for Cyclic Operads
arXiv:math/0312231
Abstract
We introduce the notion of homotopy inner products for any cyclic quadratic Koszul operad , generalizing the construction already known for the associative operad. This is done by defining a colored operad , which describes modules over with invariant inner products. We show that satisfies Koszulness and identify algebras over a resolution of in terms of derivations and module maps. An application to Poincaré duality on the chain level of a suitable topological space is given.
