Title
Edge-Distinguishing Index of a Graph
Abstract
We introduce a concept of edge-distinguishing colourings of graphs. A closed neighbourhood of an edge $${e\in E(G)}$$ e E ( G ) is a subgraph N [ e ] induced by e and all edges adjacent to it. We say that a colouring c : E ( G ) C does not distinguish two edges e 1 and e 2 if there exists an isomorphism of N [ e 1] onto N [ e 2] such that ( e 1) = e 2 and preserves colours of c . An edge-distinguishing index of a graph G is the minimum number of colours in a proper colouring which distinguishes every two distinct edges of G . We determine the edge-distinguishing index for cycles, paths and complete graphs.
