We study how quantum field theory models are modified under the reparametrizations of the space-time coordinates and some simultaneous transformations of the field function. The transformations that turn the action of the massive field in the Minkowski space-time into the action of the massless field in some curved space are presented.
Keywords: Klein–Gordon–Fock equation reparametrization of the space-time transformation of field functions.
