素数平方次数的可迁置换群

Transitive permutation groups of prime-squared degree

Edward Dobson, Dave Witte

摘要:

本文明确地确定了所有的p-平方次传递群,p是素数,其Sylow p-子群不是两个p阶循环群的圈积。此外,我们给出了Sylow p-子群是这样一个圈积的p-平方次传递群的一般描述,并明确地确定了其中的大多数。作为应用,我们解决了p-平方阶交换群的Cayley对象的Cayley同构问题,明确地确定了p-平方阶阿贝尔群的Cayley图的全自同构群,并找到了所有p-平方阶非正规Cayley图.

英文摘要:

We explicitly determine all of the transitive groups of degree p-squared, p a prime, whose Sylow p-subgroup is not the wreath product of two cyclic groups of order p. Furthermore, we provide a general description of the transitive groups of degree p-squared whose Sylow p-subgroup is such a wreath product, and explicitly determine most of them. As applications, we solve the Cayley Isomorphism problem for Cayley objects of an abelian group of order p-squared, explicitly determine the full automorphism group of Cayley graphs of abelian groups of order p-squared, and find all nonnormal Cayley graphs of order p-squared.
