In this paper we consider the generalized surface quasi-geostrophic α-SQG equations, in the "sublinear regime" α∈(0,1) and we study the stability of vortex patches close to vortex discs.

Abstract
In this paper we consider the generalized surface quasi-geostrophic α-SQG equations, in the "sublinear regime" α∈(0,1) and we study the stability of vortex patches close to vortex discs.
