DIRAC SEA AND HOLE THEORY FOR BOSONS II: RENORMALIZATION APPROACH
DIRAC SEA AND HOLE THEORY FOR BOSONS II: RENORMALIZATION APPROACH
In bosonic formulation of the negative energy sea, so-called Dirac sea presented in the preceding paper [arXiv:hep-th/0603242], one of the crucial points is how to construct a positive definite inner product in the negative energy states, since naive attempts would lead to nonpositive definite ones. In the preceding paper, the …
