Abstract
The field-theoretical gauge model for a superconductor, generalized to a n/2-component complex order parameter, is renormalized in two-loop order. The question of a fluctuation-induced first-order transition is discussed, and the crossover functions for the effective exponents and the amplitude ratio of the specific heats above and below are given.
