AbstractIn this talk, I will consider isomorphisms of Bergman fans of matroids. Motivated by algebraic geometry, these isomorphisms can be considered as matroid analogs of birational maps. I will introduce Cremona automorphisms of the coarsest fan structure. These produce a class of automorphisms which do not come from automorphisms of the underlying matroid. I will then explain that the automo...
Website：http://www.tsimf.cn/meeting/detail?id=360 The purpose of this international workshop is to review some of the advances in algebraic geometry in recent years. We hope to cover areas as wide as birational geometry, moduli theory, enumerative geometry, mirror symmetry and related topics and hope to foster further connections between these areas.SpeakersCaucher BirkarTsinghua UniversityArt...
