The paper puts forward sufficient conditions for a mapping from Rn to Rn to be a global homeomorphism. As an application, the Hadamard theorem for differentiable mappings and conditions for the existence and uniqueness of a coincidence point of a covering mapping and a Lipschitz mapping on Rn are derived. Covering mappings of metric spaces and mappings covering at a point are studied. Bibliography: 23 titles. © 2019 Russian Academy of Sciences (DoM), London Mathematical Society, Turpion Ltd.
