DESCRIPTION:Speaker: Lauro Silini\nhosted by Jan Maas\nAbstract: Hoskins' s
 emigeostrophic equation is one of the most effective meteorological model 
 that represents the formation of transported interfaces (frontogenesis) ov
 er the earth. We will present its surprising connection with the theory o
 f optimal transportation when studied in the periodic and flat case\, and 
 highlight the major difficulties to extend this argument in the curved set
 ting. We prove local-in-time existence of smooth solutions in subdomains 
 of a rotating sphere taking advantage of an alternative approach based on 
 peculiar cancellation properties intrinsic in the equation's structure.
