Equitable List Coloring of Graphs with Bounded Degree

Abstract

AbstractA graph G is equitably k‐choosable if for every k‐list assignment L there exists an L‐coloring of G such that every color class has at most vertices. We prove results toward the conjecture that every graph with maximum degree at most r is equitably ‐choosable. In particular, we confirm the conjecture for and show that every graph with maximum degree at most r and at least r3 vertices is equitably ‐choosable. Our proofs yield polynomial algorithms for corresponding equitable list colorings.
