Abstract
It is shown that the order parameter fluctuations result in a power de pendence of the superconducting transition temperature in quasi-2D met als on the probability of fermion hopping between layers. The dependen ce of this temperature on the carrier concentration is determined for a model with indirect attraction between carriers. It is found that th e transition takes place at temperatures lower than those expected fro m the BCS theory. (C) 1998 American Institute of Physics. [S1063-777X( 98)00908-6].
