Jianmin Ma, Kaishun Wang
In [H. Suzuki, Association schemes with multiple -polynomial structures, J. Algebraic Combin. 7 (1998) 181-196], Suzuki gave a classification of association schemes with multipl…
Orthogonal graphs over Galois rings of odd characteristic
Fenggao Li, Jun Guo, Kaishun Wang
Assume that is a positive integer and or . In this paper we introduce the orthogonal graph over a Galois ring of odd characteristic and prove that it is…
