In this joint work with Marci Hablicsek and Leo Herr, we investigate an adaptation of the notion of Hochschild co/homology for logarithmic schemes, encoding their combinatorics and administrating mild singularities. We set up a geometric framework to prove the Hochschild-Kostant-Rosenberg isomorphism and some desirable properties of this invariant in this logarithmic version.
