Approximative maps obtained as limits of sequences of shape equivalences are strongly accessible. It is proved that strongly accessible approximative maps induce pseudo-isomorphisms in the sense of H. Kato. It is also seen that, under the assumption of calmness, shape morphisms induced by accessible approximative maps are left invertible. As an application some results of L. Boxer concerning approximately invertible maps are generalized. 0166-8641 10.1016/0166-8641(86)90039-8 https://hdl.handle.net/20.500.14352/64692 http://www.sciencedirect.com/science/article/pii/0166864186900398 http://www.sciencedirect.com/ On limits of shape maps
