Abstract

In 1993, Chemin proved that vorticity possessing negative Holder regularity in directions given by a sufficient family of vector fields (striated regularity) maintains such regularity for all time when measured against the push-forward of those vector fields. Later work of Gamblin and Saint Raymond, and of Danchin, established analogous results in higher dimension. We give an alternative proof of these results, and establish the propagation of striated regularity of the Lagrangian velocity in a positive Holder space.
