簇剖分的局部$h$ -多项式只有实零点

The Local $h$-Polynomials of Cluster Subdivisions Have Only Real Zeros

Philip B. Zhang

摘要:

Athanasiadis提出的问题是否本地$h$多项式类型$A$集群细分只有真正的零。本文证实了这一猜想,并证明了局部$h$ -多项式对所有其它Cartan-Killing型的实根性.我们的证明主要涉及乘子序列和第二类切比雪夫多项式。

英文摘要:

Athanasiadis raised the question whether the local $h$-polynomials of type $A$ cluster subdivisions have only real zeros. In this paper, we confirm this conjecture and prove the real-rootedness of local $h$-polynomials for all the other Cartan--Killing types. Our proofs mainly involve multiplier sequences and Chebyshev polynomials of the second kind.
