Abstract
By means of Monte Carlo simulations and Coulomb-gas scaling it is shown that the vortex fluctuations in the three-dimensional anisotropic XY model become effectively two dimensional just above the critical temperature. This suggests that the resistance scaling function in the case of high-Tc superconductors should be identical to the one for conventional superconducting films. Some experimental evidence for this is pointed out.
