Gravier–Maffray list-coloring conjecture for claw-free graphs

From papers

A graph is claw-free if it has no induced subgraph isomorphic to K1,3K_{1,3}. Let χ(G)\chi(G) and χ(G)\chi_\ell(G) denote the chromatic and list chromatic numbers. Gravier–Maffray's conjecture. For every claw-free graph GG,

χ(G)=χ(G).\chi_\ell(G)=\chi(G).

This is the broad chromatic-choosability conjecture for claw-free graphs; the supplied text does not resolve it in general.
