我们找到了Boros-Moll多项式的系数Pm(A)的部分双色排列的一个组合设置。利用这个模型,我们给出了Pm(A)系数递推关系的一个组合证明。这种方法使我们能够给出Pm(A)的对数凹性的组合解释,Pm(A)是由Moll猜想的,并得到Kauers和Paule的证实。
We find a combinatorial setting for the coefficients of the Boros–Moll polynomialsPm(a) in terms of partially 2-colored permutations. Using this model, we give a combinatorial proof of a recurrence relation on the coefficients ofPm(a). This approach enables us to give a combinatorial interpretation of the log-concavity ofPm(a) which was conjectured by Moll and confirmed by Kauers and Paule.
