WorkshopThe one-day workshop will discuss several foundational aspects of Grothendieck's Quot schemes, the moduli space of coherent systems, and especially the sheaf stable pairs theory, and explore the interaction between these constructions and Enumerative algebraic geometry and Birational geometry.SpeakersCaucher Birkar ( YMSC & BIMSA )Chandranandan Gangopadhyay ( IISER Pune )Hyeonjun Park (...
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...
