关于欧拉函数的几点注记

Some remarks on Euler's totient function

Rodney Coleman

摘要:

欧拉函数的图像由数字1和偶数组成。然而,许多偶数不在图像中。我们考虑找到图像中的那些偶数和那些不在图像中的偶数的问题。如果图像中有一个偶数,那么它的原像最多可以有一半的元素是奇数。但是,它可能只包含偶数。我们考虑的结构的原像的某些数字的形象的totient函数。

英文摘要:

The image of Euler's totient function is composed of the number 1 and even numbers. However, many even numbers are not in the image. We consider the problem of finding those even numbers which are in the image and those which are not. If an even number is in the image, then its preimage can have at most half its elements odd. However, it may contain only even numbers. We consider the structure of the preimage of certain numbers in the image of the totient function.
