Algorithm for finding vertex-edge domination number on graphs with bounded treewidth and related problems on planar graphs

Yichen Wang, Haixiang Zhang, Mei Lu

Given a graph , a vertex {\em ve-dominates} all edges incident to any vertex of . A set is a {\em ve-dominating set} if for all edges $e\…

Extremal results on Berge disjoint paths

Xiamiao Zhao, Yiyan Zhan, Mei Lu

The well-known Erdős-Gallai Theorem gave the Turán number of paths. Bushaw and Kettle generalized this result to consider the Turán number of disjoint paths. Since then, many studi…

Turán type problems for a fixed graph and a linear forest

Haixiang Zhang, Xiamiao Zhao, Mei Lu

Let be a family of graphs. A graph is -free if does not contain any as a subgraph. The Turán number, denoted by $ex(n, \mathsc…

Partite saturation number of cycles

Yiduo Xu, Zhen He, Mei Lu

A graph is said to be -saturated relative to , if does not contain any copy of , but the addition of any edge in would create a copy of $…
