A (k,t)-track layout of a graph G consists of a (proper) vertex t-colouring of G, a total order of each vertex colour class, and a (non-proper) edge k-colouring such that between each pair of colour classes no two monochromatic edges cross.

A PROCEDURE FOR DERIVING ODD-GRACEFUL CHROMATIC NUMBERS OF GRAPHS
Let \(G:=(V,E)\) be an undirected finite simple graph with vertex set \(V\) and edge set \(E\). A function \(c:V(G)\rightarrow \{1,2,\ldots,k\},\) for some positive integer \(k\), such that \(c(u)\neq c(v)\) for every edge \(uv\in E(G)\), is called a ...

A facial parity edge colouring of a connected bridgeless plane graph is an edge colouring in which no two face-adjacent edges (consecutive edges of a facial walk of some face) receive the same colour, in addition, for each face α and each colour c, either no edge or an odd number of edges incident with α is coloured with c.

A note on the vertex-distinguishing index for some cubic graphs [PDF]
The vertex-distinguishing index of a graph \(G\) (\(\operatorname{vdi}(G)\)) is the minimum number of colours required to colour properly the edges of a graph in such a way that any two vertices are incident with different sets of colours.

Let \(G_{n,p}\) be the random graph with vertex set \(V_ n=\{1,2,...,n\}\) in which the \(\binom{n}{2}\) possible edges occur independently with probability p.

Properly Edge-Coloured Subgraphs in Colourings of Bounded Degree [PDF]
The smallest \(n\) such that every coloring of the edges of the \(n\)-vertex complete graph \(K_n\) must contain a monochromatic star \(K_{1,s+1}\) or a properly edge-colored \(K_t\) is denoted by \(f(s,t)\), Its existence is guaranteed by the Erdős-Rado Canonical Ramsey theorem.
