Abstract
Thermal fluctuations of vortex lines are shown to be capable of strongly reducing the value of the critical current in the mixed state of high- superconductors. The theory of pinning in the presence of thermal fluctuations is developed. The current relaxation law in the regime of single-vortex pinning is obtained.
