Asymptotics for Palette Sparsification

Combinatorics 2023-06-02 v1

Abstract

It is shown that the following holds for each ε>0\varepsilon>0. For GG an nn-vertex graph of maximum degree DD and "lists" LvL_v (vV(G)v \in V(G)) chosen independently and uniformly from the ((1+ε)lnn(1+\varepsilon)\ln n)-subsets of {1,...,D+1}\{1, ..., D+1\}, G admits a proper coloring σ with σvLvv G \text{ admits a proper coloring } \sigma \text{ with } \sigma_v \in L_v \forall v with probability tending to 1 as DD \to \infty. This is an asymptotically optimal version of a recent "palette sparsification" theorem of Assadi, Chen, and Khanna.
