  We calculate the contribution of superconducting fluctuations to thermal
transport in the normal state, for low magnetic fields. We do so in the
Gaussian approximation to their critical dynamics which is also the
Aslamazov-Larkin approximation in the microscopics. Our results for the thermal
conductivity tensor and the transverse thermoelectric response are new. The
latter compare favorably with the data of Ong and collaborators on the Nernst
effect in the cuprates.
