Abstract：This is a partial work of an ongoing project with Jianxun Hu and Bai-Ling Wang. The goal of the project to construct a general scheme for K theory, complex (co)bordism theory and etc. for moduli spaces. In this talk, I will focus on the K theory case and explain how to construct the related theory on virtual orbifolds introduced by Tian and myself.
