2度可换群上的有向Cayley图的自同构群

THE AUTOMORPHISM GROUPS OF CAYLEY DIGRAPHS OF FINITE ABELIAN GROUP WITH DEGREE 2

在本文中，我们推广了Ｍ．Ａ．Ｆｏｉｌ［１］的关于循环群上Ｌ－形的结果．并应用得到的结论刻画了２度可换群上有向Ｃａｙｌｅｙ图的自同构群。

In this paper,we generalize an M.A.Foil's [1] result about L-shaped tiles of cyclic groups and then use it to characterize the automorphism groups of Cayley digraphs on finite Abelian groups with degree 2.
