<\/span>In this talk, I will explain our recent work on $G$-twisted version of homotopy Gerstenhaber algebraic 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 algebra 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 joint work with Weiqiang He and Si Li.<\/span>\n\t\n\t\t
