Strong Chromatic Index of Outerplanar Graphs
The strong chromatic index χs′(G) of a graph G is the minimum number of colors needed in a proper edge-coloring so that every color class induces a matching in G. It was proved In 2013, that every outerplanar graph G with Δ≥3 has χs′(G)≤3Δ−3.

A stronger bound for the strong chromatic index [PDF]
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.

Upper Bounds for the Strong Chromatic Index of Halin Graphs [PDF]
The strong chromatic index of a graph G, denoted by χ′s(G), is the minimum number of vertex induced matchings needed to partition the edge set of G. Let T be a tree without vertices of degree 2 and have at least one vertex of degree greater than 2.

The strong chromatic index of 1-planar graphs [PDF]
The chromatic index $\chi'(G)$ of a graph $G$ is the smallest $k$ for which $G$ admits an edge $k$-coloring such that any two adjacent edges have distinct colors.

Strong chromatic index and Hadwiger number [PDF]
We investigate the effect of a fixed forbidden clique minor upon the strong chromatic index, both in multigraphs and in simple graphs. We conjecture for each k ≥ 4 that any K k ‐minor‐free multigraph of maximum degree Δ has strong chromatic index at most

The Strong Chromatic Index of Complete Halin Graphs
The strong edge coloring of a graph G is an assignment of colors to the edges of G such that two distinct edges are colored differently if they are incident to a common edge or share an endpoint. The strong chromatic index of a graph G, denoted by χs′(G),

On the Strong Chromatic Index of Sparse Graphs [PDF]
The strong chromatic index of a graph $G$, denoted $\chi'_s(G)$, is the least number of colors needed to edge-color $G$ so that edges at distance at most two receive distinct colors.
