Mokameeting, Federico Stra (Pisa) & Hugo Lavenant (Orsay), May 24th 2017

Mokameeting, May 24th 2017, 10:30-12:00, room A415 Federico Stra (SNS Pisa) Title: Finiteness and continuity of multimarginal optimal transport cost Abstract: In the talk I will present some new results regarding the finiteness and continuity of the multimarginal optimal transport for a repulsive cost. We exhibit also counterexamples showing the sharpness of the finiteness condition. These …
