Abstract

The L(p, q)-Edge-Labelling problem is the edge variant of the well-known L(p, q)-Labelling problem. It is equivalent to the L(p, q)-Labelling problem itself if we restrict the input of the latter problem to line graphs. So far, the complexity of L(p, q)-Edge-Labelling was only partially classified in the literature. We complete this study for all p, q≥ 0 by showing that whenever (p, q) ≠ (0, 0 ), the L(p, q)-Edge-Labelling problem is NP-complete. We do this by proving that for all p, q≥ 0 except p= q= 0, there is an integer k so that L(p, q)-Edge-k-Labelling is NP-complete.
