Bipartite graphs with a perfect matching and digraphs

Zan-Bo Zhang, Dingjun Lou

In this paper, we introduce a corresponding between bipartite graphs with a perfect matching and digraphs, which implicates an equivalent relation between the extendibility of bipa…

Notes on factor-criticality, extendibility and independence number

Zan-Bo Zhang, Dingjun Lou, Xiaoyan Zhang

In this paper, we give a sufficient and necessary condition for a $k$ -extendable graph to be $2 k$ -factor-critical when $k = ν /4$ , and prove some results on independence numbers in $n…

Equivalence between Extendibility and Factor-Criticality

Zan-Bo Zhang, Tao Wang, Dingjun Lou

In this paper, we show that if $k \geq (ν + 2) /4$ , where $ν$ denotes the order of a graph, a non-bipartite graph $G$ is $k$ -extendable if and only if it is $2 k$ -factor-critical. If $k…
