Abstract
A new representation for the thermal Green's function of He-3-A is der ived in order to calculate a general expression for the corresponding supercurrent at an arbitrary temperature. Expansion of this general ex pression in the orbital vector gradients is considered at zero tempera ture; the widely accepted first-order contribution with the anomalous part and the second-order corrections to it are obtained, thus confirm ing the existence of the anomalous current at zero temperature.
