Singularity formation in the incompressible Euler equation in finite and infinite time
Some classical and recent results on the Euler equations governing perfect (incompressible
and inviscid) fluid motion are collected and reviewed, with some small novelties scattered …

On the relation between enhanced dissipation timescales and mixing rates
We study diffusion and mixing in different linear fluid dynamics models, mainly related to
incompressible flows. In this setting, mixing is a purely advective effect that causes a transfer …
