Abstract

Let ρ\rho be a non-negative integer. A ρ\rho-removed uniform matroid is a matroid obtained from a uniform matroid by removing a collection of ρ\rho disjoint bases. We present a combinatorial formula for Kazhdan-Lusztig polynomials of ρ\rho-removed uniform matroids, using skew Young Tableaux. Even for uniform matroids, our formula is new, gives manifestly positive integer coefficients, and is more manageable than known formulas.
