DESCRIPTION:Title: <a href="https://researchseminars.org/talk/YUAAS/19/">K
 azhdan-Lusztig Immanants for $k$-positive Matrices</a>\nby Sunita Chepuri 
 (University of Michigan) as part of York University Applied Algebra Semina
 r\n\n\nAbstract\nImmanants are matrix functionals that generalize the dete
 rminant. One notable family of immanants are the Kazhdan-Lusztig immanants
 . These immanants are indexed by permutations and are defined as sums invo
 lving Kazhdan-Lusztig polynomials specialized at $q=1$. Kazhdan-Lusztig im
 manants have several interesting combinatorial properties\, including that
  they are nonnegative on totally positive matrices. We give a condition on
  permutations that allows us to extend this theorem to the setting of $k$-
 positive matrices.\n
