Sufficient conditions for -factors and spanning trees of graphs
Guoyan Ao, Ruifang Liu, Jinjiang Yuan +2
For any integer a graph has a -factor if it contains a -regular spanning subgraph. In this paper we prove a sufficient condition in terms of the number of -c…
Fractional matching, factors and spectral radius in graphs involving minimum degree
Jing Lou, Ruifang Liu, Guoyan Ao
A fractional matching of a graph is a function such that for any , , where $E_{G}(v)=\{e\in E(G): e~ \mbox{…
Maxima of the -index of non-bipartite -free graphs
Ruifang Liu, Lu Miao, Jie Xue
A classic result in extremal graph theory, known as Mantel's theorem, states that every non-bipartite graph of order with size contains a tri…
Sufficient spectral conditions on Hamiltonian and traceable graphs
Ruifang Liu, Wai Chee Shiu, Jie Xue
In this paper, we give sufficient conditions on the spectral radius for a bipartite graph to Hamiltonian and traceable, which expand the results of Lu, Liu and Tian (2012) [10]. Fu…
