We study the evolution of the Hölderian regularity for some convection-diffusion equation with respect to Lipschitzian vector field, generalizing an earlier result for the Besov spaces Bp,∞s, with p finite and s ∈ (-1, 1). As an application, we show for the two-dimensional Navier-Stokes system that if the initial vorticity is a vortex patch having a C1+ε boundary then its image through the viscous flow preserves this regularity for all time with uniform control on the viscosity. We also show some results of inviscid limit.
