SUMMARY:On the construction of analytic almost-sharp front
 s for SQG - Jose Rodrigo (Warwick)

DESCRIPTION:Almost-sharp fronts for the Surface Quasi-geostrop
 hic equation are the analogous scenario to vortex 
 tubes for 3D Euler.  In this talk I will describe 
 this connection and a program in collaboration wit
 h Charles Fefferman to construct families of almos
 t-sharp fronts with arbitrarily large gradient but
  simple geometry. The existence of these families 
 can be used to understand the evolution of fronts 
 for SQG without relying on any tools not available
  in the study of isolated vortex lines for 3D Eule
 r.
