Zeta functions for tensor products of locally coprime integral adjacency algebras of association schemes

Allen Herman, Mitsugu Hirasaka, Semin Oh

The zeta function of an integral lattice $Λ$ is the generating function $ζ_{Λ} (s) = n = 0 \sum \infty a_{n} n^{- s}$ , whose coefficients count the number of left ideals of $Λ$ …

Association schemes in which the thin residue is an elementary abelian $p$ -group of rank $2$

Mitsugu Hirasaka, Kijung Kim

In this article, we investigate the existence and schurity problem of association schemes whose thin residues are isomorphic to an elementary abelian $p$ -group of rank $2$ .
