Optimal Regularity for the 2D Euler Equations in the Yudovich class
Nicola de Nitti, David Meyer, Christian Seis
We analyze the optimal regularity that is exactly propagated by a transport equation driven by a velocity field with BMO gradient. As an application, we study the 2D Euler equation…

Fine large-time asymptotics for the axisymmetric Navier--Stokes equations
Christian Seis, Dominik Winkler
We examine the large-time behavior of axisymmetric solutions without swirl of the Navier--Stokes equation in . We construct higher-order asymptotic expansions for the…
