A precolouring extension of Vizing's theorem
2019
Journal of Graph Theory
Fix a palette of Δ + 1 colors, a graph with maximum degree Δ, and a subset M of the edge set with minimum distance between edges at least 9. If the edges of M are arbitrarily precoloured from , then there is guaranteed to be a proper edge-coloring using only colors from that extends the precolouring on M to the entire graph. This result is a first general precolouring extension form of Vizing's theorem, and it proves a conjecture of Albertson and Moore under a slightly stronger distance
