In nonmonotonic logic, injective preferential models play an important role.

Let f be a covering mapping of a compact manifold M without boundary. It is shown that the necessary and sufficient condition of the quasi-hyperbolic covering mapping of f is that ( I-f) is injective and has closed range.

设f是紧致不带边流形M上的覆盖映射，证明了f是拟双曲覆盖映射的充分必要条件是（I－f＊）为单射且有闭值域。
