The International Center for Mathematical Sciences – Sofia (ICMS-Sofia) invites you to attend the webinar on Integral PL actions from birational geometry with Maxim Kontsevich, Professor at I.H.E.S., Bures-sur-Yvette, France, Distinguished Professor at University of Miami, USA.
The webinar is jointly organized with the Institute of the Mathematical Sciences of the Americas at the University of Miami.
The event will take place on Monday, August 17, 2020, at 16:00, EEST (local time in Sofia, Bulgaria).
Abstract: The group of birational automorphisms of an N-dimensional algebraic torus, preserving the standard logarithmic volume element, acts (by tropicalization) on N-dimensional real vector space by homogeneous piece-wise linear homeomorphisms. A similar construction exists for any compact Calabi-Yau variety over a non-archimedean field, through the notion of the “essential EEEE”. I’ll talk about examples coming from generalized cluster varities, and from Calabi-Yau varieties parameterizing linkages of regular graphs.
