A cross-intersection theorem for vector spaces based on semidefinite programming

Sho Suda, Hajime Tanaka

Let $F$ and $G$ be families of $k$ - and $ℓ$ -dimensional subspaces, respectively, of a given $n$ -dimensional vector space over a finite field $F_{q}$ .…

On relative $t$ -designs in polynomial association schemes

Eiichi Bannai, Etsuko Bannai, Sho Suda +1

Motivated by the similarities between the theory of spherical $t$ -designs and that of $t$ -designs in $Q$ -polynomial association schemes, we study two versions of relative $t$ -desig…
