Strong chromatic index of products of graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
The strong chromatic index of a graph is the minimum number of colours needed to colour the edges in such a way that each colour class is an induced matching.

A stronger bound for the strong chromatic index [PDF]

open access: yesElectronic Notes in Discrete Mathematics, 2015
We prove χ′s(G) ≤ 1.93 Δ(G)2 for graphs of sufficiently large maximum degree where χ′s(G) is the strong chromatic index of G. This improves an old bound of Molloy and Reed. As a by-product, we present a Talagrand-type inequality where we are allowed to exclude unlikely bad outcomes that would otherwise render the inequality unusable.

On the upper chromatic index of a multigraph [PDF]

open access: yesComputer Science Journal of Moldova, 2002
We consider the colorings of the edges of a multigraph in such a way that every non-pendant vertex is incident to at least two edges of the same color.

On the mod $k$ chromatic index of graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
For a graph $G$ and an integer $k\geq 2$, a $\chi'_{k}$-coloring of $G$ is an edge coloring of $G$ such that the subgraph induced by the edges of each color has all degrees congruent to $1 ~ (\mod k)$, and $\chi'_{k}(G)$ is the minimum number of colors ...
