Abstract
It is shown that the particular form of the mass current in 3He-A found by Cross (1975) is equivalent to a phenomenological assumption that the current depends only on the traceless part of the tensor Omega ij introduced by Mermin and Ho (1976) to describe spatial variations of the order parameter. An equation of motion for Omega ij is derived in terms of the vector C introduced previously by the author (1975) to describe temporal variations of the order parameter. The appropriate generalizations of curl nu s=0 and the quantization of circulation for 3He-A are derived in terms of Omega ij, and the nature of possible singularities is discussed.Keywords
