Dear Colleagues , Arturo Kohatsu-Higa (Ritsumeikan, Kyoto), Valentin Konakov (HSE, Moscow) and myself are organizing a conference entitled "Perturbation Techniques in Stochastic Analysis and Its Applications" which will take place at the CIRM in Marseille France from March 11th to March 15th 2019. The following lectures are scheduled: - François Delarue (Université de Nice) "Smoothing effects for McKean-Vlasov equations" - Benjamin Jourdain (ENPC, Cermics) "Stochastic Differential Equations with rank based mean-field interaction" - Stanislav Molchanov (UNC, Charlotte et HSE Moscou) "Perturbation problems in population dynamics" - Michaël Röckner (Université de Bielefeld) "Monotonicity methods for SPDE, including the time fractional case" The detailed program is available on the conference webpage: [ https://conferences.cirm-math.fr/1979.html | https://conferences.cirm-math.fr/1979.html ] where it is possible as well to register. The participants are limited to 40. All the best, S. Menozzi
