## Abstract We show that the following problem is __NP__ complete: Let __G__ be a cubic bipartite graph and __f__ be a precoloring of a subset of edges of __G__ using at most three colors. Can __f__ be extended to a proper edge 3βcoloring of the entire graph __G__? This result provides a natural co
## Abstract In the edge precoloring extension problem, we are given a graph with some of the edges having preassigned colors and it has to be decided whether this coloring can be extended to a proper __k__βedgeβcoloring of the graph. In list edge coloring every edge has a list of admissible colors,
