Abstract
The well-known discrepancies between covariant and non-covariant forma lisms in quantum field theory and quantum cosmology are analyzed by fo cusing on the Coulomb gauge for vacuum Maxwell theory. On studying a f lat Euclidean background with boundaries, the corresponding mode-by-mo de analysis of one-loop quantum amplitudes agrees with the results of the Schwinger-DeWitt technique and of mode-by-mode calculations in rel ativistic gauges.
