Abstract:We establish two new estimates for a transport-diffusion equation. As an application we treat the problem of global persistence of the Besov regularity $$B_{p,1}^{frac{2}{p}+1},$$ with $$p in ]2,+infty]$$ , for the two-dimensional Navier–Stokes equations with uniform bounds on the viscosity. We provide also an inviscid global result.
