On a 1D transport equation with nonlocal velocity and supercritical dissipation. (English) Zbl 1286.35058
Summary: We study a 1D transport equation with nonlocal velocity. First, we prove eventual regularization of the viscous regularization when dissipation is in the supercritical range with non-negative initial data. Next, we will prove global regularity for solutions when dissipation is slightly supercritical. Both results utilize a nonlocal maximum principle.
