Uniformly Weighted Star-Factors of Graphs

Yunjian Wu, Qinglin Yu

A {\it star-factor} of a graph is a spanning subgraph of such that each component of which is a star. An {\it edge-weighting} of is a function $w: E(G)\longrightarrow \…

Star-uniform Graphs

Mikio Kano, Yunjian Wu, Qinglin Yu

A {\it star-factor} of a graph is a spanning subgraph of such that each of its component is a star. Clearly, every graph without isolated vertices has a star factor. A grap…

Generalization of matching extensions in graphs (II)

Zemin Jin, Huifang Yan, Qinglin Yu

Proposed as a general framework, Liu and Yu(Discrete Math. 231 (2001) 311-320) introduced -graphs to unify the concepts of deficiency of matchings, -factor-criticality…
