带有一个狄利克雷特征的Menon-Sury恒等式
Menon-Sury’s Identity with a Dirichlet Character
摘要: Li, Hu和Kim[1]运用整数剩余类环及其单位群的滤链证明了Menon-Sury恒等式的如下推广:
, 其中φ是欧拉φ函数, ,且χ是一个模n的导子为d的狄利克雷特征。在本文中,我们运用狄利克雷特征的正交性和初等计算去重新证明上述等式[2]。
Abstract: Li, Hu and Kim [1] proved the following generalization of the Menon-Sury identity by using the filtrations of the ring   Znand its unit group Z*n:
, where φ is Euler’s Totient function, , and χ is a Dirichlet character mod n with conductor d. In this paper, we re-prove the above identity based the orthogonality of Dirichlet characters and elementary calculations [2].
