Characterizations of regularity for certain $Q$ -polynomial association schemes

Sho Suda

It is shown that linked systems of symmetric designs with $a_{1}^{*} = 0$ and mutually unbiased bases (MUB) are triply regular association schemes. In this paper, we characterize triple…

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

Sho Suda

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 Kre…
