Title: Hardness of finding large independent sets in three-colorable graphs.

Abstract: We prove that, for every fixed $0{}lt {}delta{}lt 1/3$, it is NP-hard to distinguish three-colorable graphs from graphs in which every independent set has fewer than δ times the number of vertices. Consequently, for every fixed integer c ≥ 3, finding a proper c-coloring of a three-colorable graph is NP-hard.
