Erdős-Gallai-Type Results for Total Monochromatic Connection of Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2019
A graph is said to be total-colored if all the edges and the vertices of the graph are colored. A total-coloring of a graph is a total monochromatically-connecting coloring (TMC-coloring, for short) if any two vertices of the graph are connected by a ...

A note on nowhere-zero 3-flow and Z_3-connectivity

open access: yes, 2014
There are many major open problems in integer flow theory, such as Tutte's 3-flow conjecture that every 4-edge-connected graph admits a nowhere-zero 3-flow, Jaeger et al.'s conjecture that every 5-edge-connected graph is $Z_3$-connected and Kochol's ...

Sufficient Conditions for Maximally Edge-Connected and Super-Edge-Connected Graphs Depending on The Clique Number

open access: yesDiscussiones Mathematicae Graph Theory, 2019
Let G be a connected graph with minimum degree δ and edge-connectivity λ. A graph is maximally edge-connected if λ = δ, and it is super-edgeconnected if every minimum edge-cut is trivial; that is, if every minimum edge-cut consists of edges incident with

The Path-Pairability Number of Product of Stars

open access: yesDiscussiones Mathematicae Graph Theory, 2019
The study of a graph theory model of certain telecommunications network problems lead to the concept of path-pairability, a variation of weak linkedness of graphs.

Properties of uniformly $3$-connected graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
A graph on at least ${{k+1}}$ vertices is uniformly $k$-connected if each pair of its vertices is connected by $k$ and not more than $k$ independent paths.

The power of many colours

open access: yesForum of Mathematics, Sigma
A classical problem, due to Gerencsér and Gyárfás from 1967, asks how large a monochromatic connected component can we guarantee in any r-edge colouring of $K_n$ ?
