Is there a place where there is a full proof of the Hochschild–Kostant–Rosenberg theorem for Hochschild cohomology? I am aware of many places where the result is proven for Hochschild homology, i.e., Weibel, Ginzburg’s notes, etc. But I haven’t found a place where it’s proven for cohomology. Thanks!
