摘要
使用Bidwell和Curran在2006年引入的描述半直积的自同构的矩阵方法,结合作者等人在2010年证明的关于稳定自同构群的矩阵公式,得到了一类正则圈积的自同构群的矩阵描述,并求出了自同构群的阶.
It is obtained a matrix description of automorphism groups and its order for certain regular wreath products, by using the matrix method to characterize automorphisms of semi-direct products introduced by Bidwell and Curran in 2006, combined with a matrix formula for stable automorphism groups presented by the authors in 2010.
