It is shown how these fluctuations drive a sign change in the Hall coefficient $R_\\mathrm{H}$ for low magnetic fields near the superconducting transition. The scaling behaviours as a function of distance to the transition $\\epsilon=\\ln(T/T_\\mathrm{c})$ of the longitudinal ($\\sigma_\\mathrm{xx}$) and transverse ($\\sigma_\\mathrm{xy}$) conductivity is found to be consistent with Gaussian fluctuation theory.
