Regularization and renormalization of a massive vector field in a Friedman metric

Il Nuovo Cimento A, 1982
A regularized and renormalized massive-vector-field theory in a Friedmann space-time is formulated. A comparison with the scalar (and spinor) cases is performed. This formulation may be of some relevance for the very early phases of the expansion of the Universe in relation with the possibility that gauge field quanta are created because of curvature ...

Vertex renormalization, regularization and inhomogeneous flows

AIP Conference Proceedings, 2010
We describe a propagator renormalized, non‐Markovian closure for inhomogeneous turbulent flows with particular emphasis on the role of the bare vertex terms. We outline a regularization procedure as an approximation to a formal vertex renormalization and comment on numerical and analytic investigations to higher order corrections.

Uniqueness of renormalized quantities in dimensional regularization

Physical Review D, 1976
It is proved that in any order of perturbation expansion the dimensionally regularized Feynman integration may be multiplied by an arbitrary analytic function of the space-time dimension, which can be absorbed in the redefinition of the bare coupling constants so that the finite renormalized quantities are unchanged.

Analytic Regularization and Renormalization of Nonperturbation Theories

1983
Quantum field theories suffer from infinities. In perturbation theories, these infinities manifest themselves as ultraviolet (UV) divergences in Feynman integrals. In massless theories, there are also Infrared (IR) divergences to contend with. In perturbation expansion, the order-by-order removal of these infinities - the renormalization program1) - is
