Bipartite Toughness and k ‐Factors in Bipartite Graphs
Guizhen Liu, Jianbo Qian, Jonathan Z. Sun, Rui Xu
Source abstract
We define a new invariant t B ( G ) in bipartite graphs that is analogous to the toughness t ( G ) and we give sufficient conditions in term of t B ( G ) for the existence of k ‐factors in bipartite graphs. We also show that these results are sharp.
