On Radio Connection Number of Graphs
Given a graph G and a vertex coloring c, G is called l-radio connected if between any two distinct vertices u and v there is a path such that coloring c restricted to that path is an l-radio coloring.

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

A Sufficient Condition for Graphs to Be Super K-Restricted Edge Connected
For a subset S of edges in a connected graph G, S is a k-restricted edge cut if G − S is disconnected and every component of G − S has at least k vertices.

Arc Fault Tolerance of Cartesian Product of Regular Digraphs on Super-Restricted Arc-Connectivity
Let D = (V (D),A(D)) be a strongly connected digraph. An arc set S ⊆ A(D) is a restricted arc-cut of D if D − S has a non-trivial strong component D1 such that D − V (D1) contains an arc.

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

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
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]
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.
