Abstract: In this talk, I will explain our recent work on G-twisted version of homotopy Gerstenhaber alge- braic structure on Hochschild cochains of curved algebras. We give explicit cup product formula for all invertible singularities with arbitrary orbifold group G. This computes G-Frobenius alge- bra for general orbifold Landau-Ginzburg B-models, which is conjectured to be mirror to that of FJRW’s counting of Witten’s equation. This is a joint work with Weiqiang He and Si Li.
