Ill-posedness and non existence results for the generalized SQG equation

In this talk we present recent results on the existence of solutions of the generalized Surface Quasi-geostrophic equations (gSQG) that initially are in \(C^k\), \(C^{k,γ}\) or in supercritical Sobolev spaces, but lose that prescribe regularity for \(t>0\). This is a joint work with Luis Martinez-Zoroa.
