© 2020, Springer-Verlag GmbH Germany, part of Springer Nature.Given an algebra with a group G-action, we construct brace structures for its G-twisted Hochschild cochains. An an application, we construct G-Frobenius algebras for orbifold Landau–Ginzburg B-models and present explicit orbifold cup product formula for all invertible polynomials11sciescopu
