A curvature notion for planar graphs stable under planar duality
Yohji Akama, Bobo Hua, Yanhui Su +1
Woess \cite{Woess98} introduced a curvature notion on the set of edges of a planar graph, called -curvature in our paper, which is stable under the planar duality. We study geom…
Large book--cycle Ramsey numbers
Qizhong Lin, Xing Peng
Let be the book graph which consists of copies of all sharing a common , and let be a cycle of length . In this paper, we first determine th…
Packing branchings under cardinality constraints on their root sets
Hui Gao, Daqing Yang
Edmonds' fundamental theorem on arborescences characterizes the existence of pairwise arc-disjoint spanning arborescences with prescribed root sets in a digraph. In this paper,…
Planar graphs without normally adjacent short cycles
Fangyao Lu, Mengjiao Rao, Qianqian Wang +1
Let be the class of plane graphs without triangles normally adjacent to -cycles, without -cycles normally adjacent to -cycles, and without normally a…
On coloring numbers of graph powers
H. A. Kierstead, Daqing Yang, Junjun Yi
The weak -coloring numbers of a graph were introduced by the first two authors as a generalization of the usual coloring number , and have since found in…
