Abstract
The Gaussian theory of superconducting fluctuations in an uniform magn etic field is presented above the H-c2 line, for an anisotropic superc onductor. The situation of an arbitrary orientation of the field is in vestigated by means of a scaling transformation. The specific heat and the diamagnetic susceptibility are calculated. In particular the fluc tuation torque is compared to the mean-field one just below H-c2 and i n the London regime. A comparison is made with existing experiments on specific heat and torque in high-T-c compounds.
