模Fibonacci数乘性逆的Zeckendorf表示

Zeckendorf representation of multiplicative inverses modulo a Fibonacci number

Gessica Alecci, Nadir Murru, Carlo Sanna

摘要:

Prempreesuk、Noppakaew和Pongsriiam确定了$2$模$F_n$的乘法逆的Zeckendorf表示,对于每个不能被$3$整除的正整数$n$,其中$F_n$表示第$n$个斐波那契数。对每个固定整数$a \geq 3$和所有正整数$n$与$\gcd(a, F_n) = 1$,我们确定了$a$模$F_n$的乘法逆的Zeckendorf表示.我们的证明利用了实数的基$φ$展开。

英文摘要:

Prempreesuk, Noppakaew, and Pongsriiam determined the Zeckendorf representation of the multiplicative inverse of $2$ modulo $F_n$, for every positive integer $n$ not divisible by $3$, where $F_n$ denotes the $n$th Fibonacci number. We determine the Zeckendorf representation of the multiplicative inverse of $a$ modulo $F_n$, for every fixed integer $a \geq 3$ and for all positive integers $n$ with $\gcd(a, F_n) = 1$. Our proof makes use of the so-called base-$φ$ expansion of real numbers.
