摘要
Kinetic equation for excess Cooper pairs above T-c is derived within the framework of Time Dependant Ginzburg-Landau (TDGL) theory. Fluctuation correction to Hall conductivity sigma(xy)((2D)) and critical correction to Nernst coefficient nu(xy)((2D)) are calculated for the case of weak magnetic field. The comparison with the BCS result by Varlamov and Livanov [A. A. Varlamov and D. V. Livanov Phys. Lett. A157 (1991) 519] gives the final determination of the all coefficients oi the phenomenological TDGL theory.
