Integral Cayley Graphs Generated by Distance Sets in Vector Spaces over Finite Fields

[摘要] Si Li and the fourth listed author (2008) considered unitary graphs attached to the vector spaces over finite rings using an analogue of the Euclidean distance. These graphs are shown to be integral when the cardinality of the ring is odd or the dimension
