De Rham Cohomology in Constrained Physical System
摘要
In this chapter, we exploit ’t Hooft-Polyakov monopole to construct closed algebra of quantum field operators and BRST charge Q. In a first class configuration of Dirac quantization, by including Q-exact gauge fixing term and Faddeev-Popov ghost term, we find the BRST invariant Hamiltonian to investigate de Rham cohomology group structure for the monopole system.
