线性递归序列的广义Cullen数

Generalized Cullen Numbers in Linear Recurrence Sequences

Yuri Bilu, Diego Marques, Alain Togb\' e

摘要:

卡伦数是$m2^m+1$形式的数,其中$m$是正整数。在2004年,Luca和St \u证明了Cullen序列中最大的Fibonacci数是$F_4=3$。实际上,他们在一些二元递归序列中寻找广义库伦数。本文将研究高阶递归序列。对于给定的线性递归$(G_n)_n$,在弱假设下,和给定的多项式$T(x)\in \mathbb{Z}[x]$,我们将证明,如果$G_n=mx^m+T(x)$,则\[ m\ll\log \log |x|\log^2(\log \log |x|)\ \mbox{and}\ n\ll\log |x|\log\log |x|\log^2(\log \log |x|), \],其中隐含常数仅取决于$(G_n)_n$和$T(x)$。

英文摘要:

A Cullen number is a number of the form $m2^m+1$, where $m$ is a positive integer. In 2004, Luca and St\u anic\u a proved, among other things, that the largest Fibonacci number in the Cullen sequence is $F_4=3$. Actually, they searched for generalized Cullen numbers among some binary recurrence sequences. In this paper, we will work on higher order recurrence sequences. For a given linear recurrence $(G_n)_n$, under weak assumptions, and a given polynomial $T(x)\in \mathbb{Z}[x]$, we shall prove that if $G_n=mx^m+T(x)$, then \[ m\ll\log \log |x|\log^2(\log \log |x|)\ \mbox{and}\ n\ll\log |x|\log\log |x|\log^2(\log \log |x|), \] where the implied constant depends only on $(G_n)_n$ and $T(x)$.
