DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HAeS/28/">In
 tegro-differential operators and nonlocal diffusion</a>\nby Fernando Soria
  (Universidad Autónoma de Madrid) as part of Harmonic analysis e-seminars
 \n\n\nAbstract\nBy a nonlocal diffusion equation we mean an evolution prob
 lem where the un-\nknown function is not just reverting to its infinitesim
 al average\, but instead it\n\nis influenced by its values at many scales.
  It is still a diffusion\, but trying to\nrevert now to an integral averag
 e of its surrounding values.\nTypical examples in probability arise when c
 onsidering jump (Levy) processes\nin optimal control\, game theory and fin
 ance. The quasi-geostrophic equation\nfor ocean-atmosphere interaction pro
 vides a ’simple’ model in fluid dynamics.\n\nIn this talk we will pres
 ent a\, by no means exhaustive\, survey describing how\nthis theory has ev
 olved in recent years.\n
