DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OCAS/20/">Gr
 assmannians\, Cluster Algebras and Hypersurface Singularities</a>\nby Sira
  Gratz (University of Glasgow) as part of Online Cluster Algebra Seminar (
 OCAS)\n\n\nAbstract\nGrassmannians are objects of great combinatorial and 
 geometric beauty\, which arise in myriad contexts. Their coordinate rings 
 serve as a classical example of cluster algebras\, and their combinatorics
  is intimately related to algebraic and geometric concepts such as to repr
 esentations of algebras and hypersurface singularities. \n\nIn this talk\,
  we take these ideas to the limit to explore the a priori simple question:
  What happens if we allow infinite clusters? In particular\, we discuss th
 e notion of a cluster algebra of infinite rank (based on joint work with G
 rabowski)\, and of a Grassmannian category of infinite rank (based on join
 t work with August\, Cheung\, Faber and Schroll).\n
