目的 研究一个包含Smarandache函数的对偶函数及其伪Smarandache函数方程的可解性。方法 利用初等及组合方法。结果给出了该方程的所有正整数解。结论 证明了该方程的所有奇数解必为奇素数P的方幂;而6是该方程惟一的偶数解。
Aim To study the positive integer solutions of a function equation involving the pseudo Smarandache function and the dual function of the Smarandache function. Methods Using the elementary and combinational method. Results All positive integer solutions are given for the equation. Conclusion It was proxed that the equation has only one even number solution n = 6, and all odd number n satisfying the equation if and only if n = pk, where p≥3 be a prime,and k be any positive integer.
