Abstract:

A $k$-proper edge-coloring of a graph $G$ is called adjacent vertex-distinguishing if any two adjacent vertices are distinguished by the set of colors appearing in the edges incident to each vertex. The smallest value $k$ for which $G$ admits such coloring is denoted by $\chi^\prime _a(G)$. We prove that $\chi^\prime_a(G)=2R+1$ for most circulant graphs $C_n([ [1,R] ])$.

Keywords:

proper edge-coloring, circulant graph, distinguishing vertices, adjacent vertex-distinguishing, chromatic number
