'This monograph presents several important concepts of quantum field theory in a different perspective and explores the consequences. If nothing else, it definitely contributes to reinforcing our understanding of current quantum field theory by separating out necessities from conventions in the formulation grounds of the theory. I am deeply convinced, however, that the additional elements presented in the book may serve a bigger purpose: the understanding of dark matter physics.'
