摘要:
最近,Glasby 和 Paseman 考虑了以下二项式和序列 $\{2^{-r}\sum_{i=0}^{r}\binom{m}{i}\}_{r=0}^{m}$,并证明了该序列是单峰的,且在 $m\in\mathbb{Z}_{\geq0}\setminus\{0,3,6,9,12\}$ 时于 $r=\lfloor\frac{m}{3}\rfloor+1$ 处取得最大值。他们还分析了当 $m$ 趋于无穷时序列最大值的渐近行为。在本工作中,我们通过考虑整数 $a \geq 1$ 的序列 $\{(1+a)^{-r}\sum_{i=0}^{r}\binom{m}{i}a^{i}\}_{r=0}^{m}$ 来推广他们的结果。我们还考虑了由该序列自然产生的一族离散概率分布。
英文摘要:
Recently, Glasby and Paseman considered the following sequence of binomial sums $\{2^{-r}\sum_{i=0}^{r}\binom{m}{i}\}_{r=0}^{m}$ and showed that this sequence is unimodal and attains its maximum value at $r=\lfloor\frac{m}{3}\rfloor+1$ for $m\in\mathbb{Z}_{\geq0}\setminus\{0,3,6,9,12\}$. They also analyzed the asymptotic behavior of the maximum value of the sequence as $m$ approaches infinity. In the present work, we generalize their results by considering the sequence $\{(1+a)^{-r}\sum_{i=0}^{r}\binom{m}{i}a^{i}\}_{r=0}^{m}$ for integers $a \geq 1$. We also consider a family of discrete probability distributions that naturally arises from this sequence.
