The Action Principle in Epstein Glaser Renormalization and Renormalization of the S-Matrix in φ4-Theory
Abstract
A formula describing finite renormalizations is derived in the Epstein-Glaser formalism and an explicit calculation of finite counterterms in 4-theory is performed. The Zimmermann identities and the action principle for changes of parameters in the interaction are presented independent of the adiabatic limit.
