The Construction of Some Association Scheme
摘要/Abstract
摘要：
设(X,{Ri}1≤i≤d)是一个有d个结合类的结合方案,从(X,{Ri}1≤i≤d)出发,理论上构作了2个类数为d的方案,计算了该方案的全部参数,并给出了用它构作的实例。另外,利用任一个给定n元集合的所有m元子集构作了一个具有多个结合类的结合方案,并计算了其全部参数。
Abstract：
Let(X,{Ri}1≤i≤d) is an association scheme with d associate classes,two theoretical metheds for costructing new association scheme with d classes from(X,{Ri}1≤i≤d),and all parameters are calculated wich above schemes, examples are given accordingly.Secondly, with all m elements subsets given by a fixed n elements set,an association scheme with several associate classes is constructed,and all the parameters are calculated accordingly.
