摘要
对任意的正整数n,S**(n)表示Smarandache双阶乘对偶函数,(n)表示Euler函数.利用初等方法研究方程S**(n)=n,(S**(n))2=2n及S**(n)=(n)的可解性,并给出了每个方程所有正整数解.
For any positive integer n, S^ * * (n) denotes Smarandache double factorial dual function, Ф (n) denotesEuler function. The main purpose of this paper is to study the positive integer solutions of equations S^** (n) = n, (S^**(n))^2 = 2n and S^** (n) = Ф(n) by using elementary methods, and give its all positive integer solutions.
