TitleHochschild homology and cohomology of Klein surfaces.
Author(s) Frederic Butin
TypeArticle in Journal
AbstractWithin the framework of deformation quantization, a first step towards the study of star-products is the calculation of Hochschild cohomology. The aim of this article is precisely to determine the Hochschild homology and cohomology in two cases of algebraic varieties. On the one hand, we consider singular curves of the plane; here we recover, in a different way, a result proved by Fronsdal and make it more precise. On the other hand, we are interested in Klein surfaces. The use of a complex suggested by Kontsevich and the help of Groebner bases allow us to solve the problem.
KeywordsHochschild cohomology; Hochschild homology; Klein surfaces; Groebner bases; quantization; star-products.
