DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AG-Davis/35/
 ">Reverse plane partitions and components of quiver Grassmannians</a>\nby 
 Joel Kamnitzer (University of Toronto) as part of UC Davis algebraic geome
 try seminar\n\n\nAbstract\nA classic result in geometric representation th
 eory relates components of Springer fibres to semistandard Young tableaux.
  I will explain how to generalize this result to reverse plane partitions.
  These RPPs are decreasing functions on a minuscule heap and they provide 
 a combinatorial model for the crystal of the coordinate ring of a minuscul
 e flag variety. Associated to the minuscule heap\, we define a module for 
 a preprojective algebra. The space of submodule of this module (called a q
 uiver Grassmannian) is isomorphic to the core of a Nakajima quiver variety
 . Our main result is that these RPPs are in bijection with the irreducible
  components of this quiver Grassmannian.\n
