Bounds on the 2-rainbow domination number of graphs
Yunjian Wu, N. Jafari Rad
A {\it 2-rainbow domination function} of a graph is a function that assigns to each vertex a set of colors chosen from the set , such that for any , $f(…
An Improvement on Vizing's Conjecture
Yunjian Wu
Let denote the domination number of a graph . A {\it Roman domination function} of a graph is a function such that every vertex with 0 has a neighb…
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…
Uniform Star-factors of Graphs with Girth Three
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. Recently, Hartnell and Rall studied a family of graphs s…
