DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SFUQNTAG/28/
 ">KP Solitons from Tropical Limits</a>\nby Claudia Fevola (MPI MiS) as par
 t of SFU NT-AG seminar\n\n\nAbstract\nIn this talk\, we present solutions 
 to the Kadomtsev-Petviashvili equation whose underlying algebraic curves u
 ndergo tropical degenerations. Riemann’s theta function becomes a finite
  exponential sum that is supported on a Delaunay polytope. We introduce th
 e Hirota variety which parametrizes all tau functions arising from such a 
 sum. After introducing solitons solutions\, we compute tau functions from 
 points on the Sato Grassmannian that represent Riemann-Roch spaces.\nThis 
 is joint work with Daniele Agostini\, Yelena Mandelshtam and Bernd Sturmfe
 ls.\n
