Weakly distance-regular digraphs whose attached association schemes are regular
Yuefeng Yang, Benjian Lv, Kaishun Wang
In this paper, we study commutative weakly distance-regular digraphs whose attached association schemes are regular, and give a characterization of mixed arcs. As an application, w…
Two bounds for generalized -connectivity of Cartesian product graphs
Hui Gao, Benjian Lv, Kaishun Wang
The generalized -connectivity of a graph , which was introduced by Chartrand et al.(1984) is a generalization of the concept of vertex connectivity. Let and $H…
Vector spaces and Grassmann graphs over residue class rings
Li-Ping Huang, Benjian Lv, Kaishun Wang
Let be the residue class ring of integers modulo , where is a prime number and is a positive integer. Using matrix representation and the inner rank…
On 3-equivalenced weakly distance-regular digraphs
Yuefeng Yang, Benjian Lv, Kaishun Wang
A weakly distance-regular digraph is 3-equivalenced if its attached association scheme is 3-equivalenced. In this paper, we classify the family of such digraphs under the assumptio…
