Abstract

Fluctuation effects of the superconducting order parameter and the critical temperature in a high-T_c oxide superconductors are investigated in connection with the mass-enhancement effect on the phenomenological Ginzburg-Landau theory and the Gaussian fluctuation theory. Large fluctuations of the order parameter caused by strong electron correlation play an essential role in the determination of T_c in high-T_c oxide superconductors.
