Abstract

We construct an embedding of any right-angled Artin group G(Δ)G(\Delta) defined by a graph Δ\Delta into a graph braid group. The number of strands required for the braid group is equal to the chromatic number of Δ\Delta. This construction yields an example of a hyperbolic surface subgroup embedded in a two strand planar graph braid group.
