A combinatorial formula for of $$\rho$$-removed uniform matroids. (English) Zbl 1450.05008
Summary: Let $$\rho$$ be a non-negative integer. A $$\rho$$-removed uniform matroid is a matroid obtained from a uniform matroid by removing a collection of $$\rho$$ disjoint bases. We present a combinatorial formula for Kazhdan-Lusztig polynomials of $$\rho$$-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.
