DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NYC-NCG/137/
 ">Nonnoetherian geometry\, noncommutative desingularizations\, and quantum
  theory</a>\nby Charlie Beil (University of Graz) as part of Noncommutativ
 e geometry in NYC\n\n\nAbstract\nI will introduce a new kind of geometry t
 hat arises from nonnoetherian subalgebras of polynomial rings\, and\, more
  generally\, coordinate rings of affine varieties. In this construction\, 
 points may be 'smeared-out' and have positive dimension. I will then descr
 ibe an application of this geometry to a class of noncommutative algebras 
 defined by oriented graphs in surfaces\, called dimer and ghor algebras. T
 he geometry allows these algebras to be viewed as noncommutative desingula
 rizations of their centers\, and yields relationships between their repres
 entation theory and the surface topology. Finally\, I will sketch an appli
 cation of the geometry to a new spacetime model of spin and its wave funct
 ion collapse.\n
