本文研究了广义考茨有向图GK(n,d)的圈数.设n = pdh,使得d m ≠| p.也令gl = gcd(dl −(− 1)l,n)。我们证明,如果以下条件之一成立:则GK(n,d)中长度为k的圈数由[公式:见正文]给出,其中μ是莫比乌斯函数。
In this paper, we count cycles in a generalized Kautz digraph GK(n,d). Let n=pdhsuch that d m ̸ |p . Also let gl=gcd(dl−(−1)l,n). We show that if one of the following conditions holds: then the number of cycles of length k in GK(n,d) is given by [Formula: see text] where μ is the Möbius function.
