论文摘要
我们介绍了矩阵的交叉点共同体学模块,并证明它满足了庞加莱二重性,硬左列施兹定理和霍奇 - 里曼的关系。作为应用,我们获得了Dowling和Wilson的最高猜想的证据,以及所有矩阵的Kazhdan-Lusztig多项式系数的非负性。
We introduce the intersection cohomology module of a matroid and prove that it satisfies Poincaré duality, the hard Lefschetz theorem, and the Hodge-Riemann relations. As applications, we obtain proofs of Dowling and Wilson's Top-Heavy conjecture and the nonnegativity of the coefficients of Kazhdan-Lusztig polynomials for all matroids.
