DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OAGAS/43/">E
 xistence of potentials for non-traditional cost functions</a>\nby Kasia Wy
 czesany (Tel Aviv University) as part of Online asymptotic geometric analy
 sis seminar\n\n\nAbstract\nIn this talk\, we will present a new approach t
 o the problem of existence of a potential for the optimal transport proble
 m and apply it to non-traditional cost functions (i.e. costs that may atta
 in infinite values). As a by-product\, we give a new transparent proof of 
 Rockafellar-Ruschendorf theorem. As an example of a non-traditional cost\,
  we discuss the polar cost\, which is particularly interesting as it induc
 es the polarity transform and the class of geometric convex functions. Thi
 s is joint work with S. Artstein-Avidan and S. Sadovsky.\n
