A Note on Eigenvalues of Cayley Graphs
Arnbjörg Soffía Árnadóttir, Chris Godsil
A graph is called integral if all its eigenvalues are integers. A Cayley graph is called normal if its connection set is a union of conjugacy classes. We show that a non-empty inte…

Strongly cospectral vertices in normal Cayley graphs
Arnbjörg Soffía Árnadóttir, Chris Godsil
We prove an upper bound on the number of pairwise strongly cospectral vertices in a normal Cayley graph, in terms of the multiplicities of its eigenvalues. We use this to determine…
