The Equivalence Principle Applicability Boundaries, Measurability, and UVD in QFT

Alexander Shalyt-Margolin

This paper presents, within the scope of the earlier introduced measurability concept, a study of the ultra-violet behavior quantum field theories. It is demonstrated that in the case of the natural assumptions there are no ultra-violet divergences in these theories. In so doing, the methods of a lattice quantum-field theory are used. Applicability of the obtained results to different energy scales is discussed.

Key words: measurability,quantum field theory,perturbation theory
