Abstract: The Hochschild-Kostant-Rosenberg (HKR) theorem relates Hochschild homology with Kahler differentials. For LG models, matrix factorization categories are analogous to the derived categories of coherent sheaves on smooth varieties. In this talk, we will discuss a Hochschild-Kostant-Rosenberg and Hirzebruch-Riemann-Roch type theorem in the context of matrix factorization categories of algebraic stacks. This talk is based on a joint work with B. Kim and D. Choa and an ongoing work with D. Choa.
