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…

Coherent configurations and triply regular association schemes obtained from spherical designs

Sho Suda

Delsarte-Goethals-Seidel showed that if $X$ is a spherical $t$ -design with degree $s$ satisfying $t \geq 2 s - 2$ , $X$ carries the structure of an association scheme. Also Bannai-Banna…
