N2 - The thermally activated resistivity, rxx, and the negative Hall resistivity, rxy are explained as two consequences of the same effect, namely the unbinding of vortex pairs in the vicinity of Tc. Both rxx and rxy exhibit a thermally activated behaviour. The activation energy depends logarithmically on the magnetic field. Our explanation suggests rxy ~raxx with a = 1 in accordance with recent measurements.
