Title : Strong Topological Rigidity of Non-Compact Orientable surfaces.
ABSTRACT. We prove that if a homotopy equivalence between any two non-compact orientable
surfaces without boundary is a proper map, then it is properly homotopic to a homeomorphism,
provided surfaces are neither the plane nor the punctured plane.
