(Joint work with Charles Fefferman) The surface quasi-geostrophic equation is a two-dimensional active scalar equation of mathematical interest because of its strong analogies with 3D Euler. We will focus on the evolution of sharp fronts (the analogue and the evolution of isolated vortex lines for 3D Euler), and study their evolution with almost-sharp fronts (families of solutions with arbitrarily large gradient and simple geometry, that exist for a time independent of the size of the gradient).
