Lambda number of the power graph of a finite group
Xuanlong Ma, Min Feng, Kaishun Wang
The power graph of a finite group is the graph with the vertex set , where two distinct elements are adjacent if one is a power of the other. An -labeling of…
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…
Strong rainbow connection numbers of toroidal meshes
Yulong Wei, Min Xu, Kaishun Wang
In 2011, Li et al. \cite{LLL} obtained an upper bound of the strong rainbow connection number of an -dimensional undirected toroidal mesh. In this paper, this bound is improved.…
