On distance matrices of distance-regular graphs
Hui Zhou, Rongquan Feng
In this paper, we give a characterization of distance matrices of distance-regular graphs to be invertible.
On -distance-transitive graphs
Hui Zhou, Cheryl Praeger, Michael Giudici +2
Distance-regular graphs have many beautiful combinatorial properties. Distance-transitive graphs have very strong symmetries, and they are distance-regular, i.e. distance-transitiv…
Directed Strongly Regular Cayley Graphs on Dihedral groups
Yiqin He, Bicheng Zhangb, Rongquan Feng
In this paper, we characterize some certain directed strongly regular Cayley graphs on Dihedral groups , where is a positive integer.
Directed Strongly Regular Cayley Graphs on Dihedral groups
Yiqin He, Bicheng Zhang, Rongquan Feng
In this paper,we construct some directed strongly regular Cayley graphs on dihedral groups,these generalizes some earlier constructions.We also characterize some certain directed s…
Perfect codes in circulant graphs
Rongquan Feng, He Huang, Sanming Zhou
A perfect code in a graph is a subset of that is an independent set such that every vertex in is adjacent to exactly one vertex in . A total…
