本文考虑分圆结合方案。本文主要研究特征p的代数闭域K上的S的邻接代数。如果,,或,我们确定SoverK的邻接代数是一个允许理想上的多项式环的商。在几种情况下,我们确定了S的标准模的不可分解直和分解。因此,我们能够计算SoverK的邻接代数的几个特定元素的p-秩。
In this paper, we consider cyclotomic association schemes. We focus on the adjacency algebra ofSover algebraically closed fieldsKof characteristicp. If,, or, we identify the adjacency algebra ofSoverKas a quotient of a polynomial ring over an admissible ideal. In several cases, we determine the indecomposable direct sum decomposition of the standard module ofS. As a consequence, we are able to compute thep-rank of several specific elements of the adjacency algebra ofSoverK.
