AI 中文摘要
我们证明了每个对称$Q$-多项式结合方案的重数构成对数凹序列。这解决了Bannai和Ito在1984年提出的单峰猜想,并确立了Stanton猜想的相关不等式。我们的证明是量子熵的强次可加性和弱单调性不等式的新应用。
英文摘要
We prove that the multiplicities of every symmetric $Q$-polynomial association scheme form a log-concave sequence. This resolves the 1984 unimodality conjecture of Bannai and Ito and establishes both related inequalities conjectured by Stanton. Our proof is a novel application of strong subadditivity and weak monotonicity inequalities for quantum entropy.
