Abstract:A 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 urn:x-wiley:03649024:media:jgt21710:jgt21710-math-0001 vertices. We prove results toward the conjecture that every graph with maximum degree at most r is equitably urn:x-wiley:03649024:media:jgt21710:jgt21710-math-0002‐choosable. In particular, we confirm the conjecture for urn:x-wiley:03649024:media:jgt21710:jgt21710-math-0003 and show that every graph with maximum degree at most r and at least r3 vertices is equitably urn:x-wiley:03649024:media:jgt21710:jgt21710-math-0004‐choosable. Our proofs yield polynomial algorithms for corresponding equitable list colorings.
Keywords:equitable coloring  list coloring  choosable  maximum degree
