On spherical designs obtained from $Q$-polynomial association schemes

Sho Suda

摘要:

我们刻画了本原幂等元$E_1$将$Q$ -多项式结合方案嵌入特征空间的映象是一个关于Krein数的球形$t$ -设计.证明了$P$ -和$Q$ -多项式格式作为球面设计的强度是有界的。

英文摘要:

We characterize that the image of the embedding of the $Q$-polynomial association scheme into eigenspace by primitive idempotent $E_1$ is a spherical $t$-design in terms of the Krein numbers. And we show that the strengths of $P$- and $Q$-polynomial schemes as spherical designs are bounded by constant.
