Extended double covers of non-symmetric association schemes of class $2$

Takuya Ikuta, Akihiro Munemasa

In this paper, we give a method to construct non-symmetric association schemes of class $3$ from non-symmetric association schemes of class $2$ . This construction is a non-symmetri…

Maximality of Seidel matrices and switching roots of graphs

Meng-Yue Cao, Jack H. Koolen, Akihiro Munemasa +1

In this paper, we discuss maximality of Seidel matrices with a fixed largest eigenvalue. We present a classification of maximal Seidel matrices of largest eigenvalue $3$ , which giv…
