Abstract

A graph GG is list point kk-arborable if, whenever we are given a kk-list assignment L(v)L(v) of colors for each vertex vV(G)v\in V(G), we can choose a color c(v)L(v)c(v)\in L(v) for each vertex vv so that each color class induces an acyclic subgraph of GG, and is equitable list point kk-arborable if GG is list point kk-arborable and each color appears on at most V(G)/k\lceil |V(G)|/k\rceil vertices of GG. In this paper, we conjecture that every graph GG is equitable list point kk-arborable for every k(Δ(G)+1)/2k\geq \lceil(\Delta(G)+1)/2\rceil and settle this for complete graphs, 2-degenerate graphs, 3-degenerate claw-free graphs with maximum degree at least 4, and planar graphs with maximum degree at least 8.
