Abstract

Symplectic reduction is the most important operation in symplectic category and there is a general principle for the symplectic reduction that is so called Q and R commutes, expressed as [Q,R]=0. Here Q stands for quantization and R stands for reduction. The famous Kirwan morphism is the R on the level of cohomology ring. In this talk we will explain how to get [Q,R]=0 for cohomology ring for the abelian case.
