Stern多项式次数序列的算术性质及相关结果

Arithmetic properties of the sequence of degrees of Stern polynomials and related results

Maciej Ulas

摘要:

令$B_{n}(t)$是$n$次Stern多项式,并令$e(n)=\op{deg}B_{n}(t)$是它的次数。在本说明中,我们继续我们的研究开始在\cite{Ul}的算术性质的序列的斯特恩多项式和序列$\{e(n)\}_{n=1}^{\infty}$。我们还研究了序列$d(n)=\op{ord}_{t=0}B_{n}(t)$。除其他事项外,我们证明,$d(n)=ν(n)$,其中$ν(n)$是2的最大功率,整除数$n$。我们还计算了方程$e(m)=i$和$e(m)-d(m)=i$在区间$[1,2^{n}]$内的解的个数。我们还得到了一个有趣的封闭表达式,一定的总和涉及斯特恩多项式。

英文摘要:

Let $B_{n}(t)$ be a $n$-th Stern polynomial and let $e(n)=\op{deg}B_{n}(t)$ be its degree. In this note we continue our study started in \cite{Ul} of the arithmetic properties of the sequence of Stern polynomials and the sequence $\{e(n)\}_{n=1}^{\infty}$. We also study the sequence $d(n)=\op{ord}_{t=0}B_{n}(t)$. Among other things we prove that $d(n)=ν(n)$, where $ν(n)$ is the maximal power of 2 which dividies the number $n$. We also count the number of the solutions of the equations $e(m)=i$ and $e(m)-d(m)=i$ in the interval $[1,2^{n}]$. We also obtain an interesting closed expression for a certain sum involving Stern polynomials.
