Remarks on geometric properties of SQG sharp fronts and $\alpha$-patches

Analysis of PDEs 2014-08-10 v2

Abstract

Guided by numerical simulations, we present the proof of two results concerning the behaviour of SQG sharp fronts and α\alpha-patches. We establish that ellipses are not rotational solutions and we prove that initially convex interfaces may lose this property in finite time.
