AI总结:

本文研究了一类基于最大公约数算法和最小性条件的特殊函数,发现其仅分为两个等价类,其中一类为恒等映射,另一类由具有素数阶数周期性的映射生成。

摘要:

在本文中,我们研究了一类在自然数集上递归定义的函数,这些函数基于两个数的最大公约数算法,并要求满足最小性条件。这些函数是排列,由无限多个依赖于自然数中某些断点的素数的循环乘积组成,以及一些具有约29.4%密度的特殊素数乘积。我们证明这些函数仅分成两个等价类(模自然等价关系下的最终相同映射):一个是恒等映射的类,另一个是由一个离散导数几乎周期性(“周期”为素数阶数)的映射生成的类。

英文摘要:

In this paper, we study a class of functions defined recursively on the set of natural numbers in terms of the greatest common divisor algorithm of two numbers and requiring a minimality condition. These functions are permutations, products of infinitely many cycles that depend on certain breaks in the natural numbers involving the primes, and some special products of primes with a density of approximately $29.4\%$. We show that these functions split into only two equivalence classes (modulo the natural equivalence relation of eventually identical maps): one is the class of the identity map and the other is generated by a map whose discrete derivative is almost periodic with ``periods" the primorial numbers.
