Covariant background field calculation of ultraviolet counterterms
F. M. de Carvalho Filho
Based on the covariant background field method, we calculate the ultraviolet counter\-terms up to two-loop order and discuss the renormalizability of the three-dimensional non-line…

Three-dimensional quantum electrodynamics as an effective interaction
E. Abdalla, F. M. de Carvalho Filho
We obtain a Quantum Electrodynamics in 2+1 dimensions by applying a Kaluza--Klein type method of dimensional reduction to Quantum Electrodynamics in 3+1 dimensions rendering the mo…
