Abstract
A nonperturbative fluctuation theory of the mixed state of two-dimensi onal type-II superconductors with finite size in the lowest Landau lev el approximation is proposed. The thermodynamic averages of the spatia l average order parameter and of the Abrikosov parameter beta(a) are c alculated. It is shown that the thermodynamic fluctuations eliminate t he Abrikosov vortex state in a wide region of the mixed state of two-d imensional type-II superconductors with real size.
