Effective actions, cutoff regularization, quasi-locality, and gluing of partition functions
A. V. Ivanov
The paper studies a regularization of the quantum (effective) action for a scalar field theory in a general position on a compact smooth Riemannian manifold. As the main method, we…

Three-loop renormalization of the quantum action for a four-dimensional scalar model with quartic interaction with the usage of the background field method and a cutoff regularization
A. V. Ivanov
The paper studies the quantum action for the four-dimensional real -theory in the case of a general formulation using the background field method. The three-loop renormalizati…
