Total-coloring of planar graphs with maximum degree 6 and without prescribed 4-cycles

Enqiang Zhu, Yangyang Zhou, Jin Xu

The Total Coloring Conjecture (TCC) is a challenging unsolved problem posed by Behzad and Vizing independently, which states that every simple graph admits a ( +2)-total-…

The Total Coloring Conjecture holds for planar graphs without three special subgraphs

Rongjin Su, Gang Fang, Enqiang Zhu

The Total Coloring Conjecture (TCC) for planar graphs with a maximum degree of six remains open. Previous studies suggest that TCC is valid for such graphs if they do not contain a…

PHEE: A phased hybrid evaluation-enhanced approach for identifying influential users in social networks

Enqiang Zhu, Haosen Wang, Yu Zhang +2

For the purpose of maximizing the spread of influence caused by a certain small number k of nodes in a social network, we are asked to find a k-subset of nodes (i.e., a seed set) w…

Metric dimension and edge metric dimension of unicyclic graphs

Enqiang Zhu, Shaoxiang Peng, Chanjuan Liu

The metric (resp. edge metric) dimension of a simple connected graph , denoted by dim (resp. edim), is the cardinality of a smallest vertex subset fo…

On a Sufficient Condition for Planar Graphs of Maximum Degree 6 to be Totally 7-Colorable

Enqiang Zhu, Chanjuan Liu, Yongsheng Rao

A total -coloring of a graph is an assignment of colors to its vertices and edges such that no two adjacent or incident elements receive the same color. The Total Coloring C…
