In this paper, we study the omega limit sets of a ray-contractive map T without the compactness assumption on the orbits. If there exists a compact subset of • K (the interior of a closed convex cone K) such that T = and T K -0 ⊂ • K, then we are able to prove that ω x either consists of a single p
