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 $\Lambda$ is the generating function ${\zeta }_{\Lambda }(s)=\sum _{n=0}^{\infty }{a}_n{n}^{-s}$, whose coefficients count the number of left ideals of $\Lambda$…
