Abstract
In this talk, I will report a paper introducing a method to investigate all possible polynomials f_add for a given non-invertible f, where f is quasihomogeneous and nondegenerate, and has a decomposition f = f_0+f_add. And if (f,Z/2Z) is Landau-Ginzburg orbifold with such non-invertible polynomialf, I'll report a method in this paper to construct a quasihomogeneus polynomial f' such that the orbifold equivalence (f,Z/2Z) ∼ (f',{id}) holds.
