Abstract
The Hochschild-Kostant-Rosenberg (HKR) isomorphism is one of the best features of Hochschild homology and cohomology, providing elegant decompositions of those. However, the resulting spaces are not always nice for varieties that are not compact. Compactification in algebraic geometry can be understood via logarithmic schemes. In this talk, I will present a joint work with Marci Hablicsek and Leo Herr devoted to adapting notions in this area and proving a logarithmic version of the HKR isomorphism.
