Neumaier Cayley graphs
Mojtaba Jazaeri
A Neumaier graph is a non-complete edge-regular graph with the property that it has a regular clique. In this paper, we study Neumaier Cayley graphs. We give a necessary and suffic…

Distance-regular graphs admitting a perfect -code
Mojtaba Jazaeri
In this paper, we study the problem that which of distance-regular graphs admit a perfect -code. Among other results, we characterize distance-regular line graphs which admit a…

Self-complementary distance-regular Cayley graphs over abelian groups
Mojtaba Jazaeri
In this paper, we study self-complementary distance-regular Cayley graphs over abelian groups. We prove that if a regular graph is self-complementary distance-regular, then it is s…
