结合方案的一个矩阵方程

A matrix equation for association schemes

Laura M. Chihara, Dennis W. Stanton

摘要:

{Let ${\Cal X}$是自对偶P-多项式关联方案。则最多有12个对角矩阵$T$,使得$(PT)^3=I$。此外,对这类格式(包括Hamming格式)的经典无限族的所有解进行了分类.

英文摘要:

{Let ${\Cal X}$ be a self-dual P-polynomial association scheme. Then there are at most 12 diagonal matrices $T$ such that $(PT)^3=I$. Moreover, all of the solutions for the classical infinite families of such schemes (including the Hamming scheme) are classified.
