DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CATGT/20/">F
 iltering Grassmannian Cohomology via k-Schur Functions</a>\nby Yuanning Zh
 ang (The University of California) as part of Applications of Combinatoric
 s in Algebra\, Topology and Graph Theory\n\n\nAbstract\nThis talk concerns
  the cohomology rings of complex Grassmannians. In $2003$\, Reiner and Tud
 ose conjectured the form of the Hilbert series for certain subalgebras of 
 these cohomology rings. We build on their work in two ways. First\, we con
 jecture two natural bases for these subalgebras that would imply their con
 jecture using notions from the theory of $k$-Schur functions. Second\, we 
 formulate an analogous conjecture for Lagrangian Grassmannians.\n
