Arc connectedness A space is said to be arc-connected or arcwise connected if any two topologically distinguishable points can be joined by an arc, which is an embedding . An arc-component of is a maximal arc-connected subset of ; or equivalently an equivalence class of the equivalence relation of whether two points can be joined by an arc or by a path whose points are topologically indistinguishable.
