Sub-exponential mixing of generalized cellular flows with bounded palenstrophy
Gianluca Crippa, Christian Schulze
We study the mixing properties of a passive scalar advected by an incompressible flow. We consider a class of cellular flows (more general than the class in [Crippa-Schulze M3AS 20…

Cellular mixing with bounded palenstrophy
Gianluca Crippa, Christian Schulze
We study the problem of optimal mixing of a passive scalar advected by an incompressible flow on the two dimensional unit square. The scalar solves the continuity equation…

Polynomial mixing under a certain stationary Euler flow
Gianluca Crippa, Renato Lucà, Christian Schulze
We study the mixing properties of a scalar advected by a certain incompressible velocity field on the two dimensional unit ball, which is a stationary radial solution of th…
