Restricted extension of sparse partial edge colorings of complete graphs

Combinatorics 2019-12-17 v1

Abstract

Given a partial edge coloring of a complete graph KnK_n and lists of allowed colors for the non-colored edges of KnK_n, can we extend the partial edge coloring to a proper edge coloring of KnK_n using only colors from the lists? We prove that this question has a positive answer in the case when both the partial edge coloring and the color lists satisfy certain sparsity conditions.
