摘要 | In this paper, we solve the rigidity problem on geodesic maps in the hyperbolic space. The main result is that a geodesic-to-geodesic injection in hyperbolic space D-n is an isometry or a composition of an isometry and an affine transformation under the Klein model if and only if it is non-degenerate. We first solve the rigidity problems on Euclidean space and the n-sphere and show that a line-to-line injection in Euclidean space R-n is an affine transformation if and only if it is non-degenerate and that a circle-to-circle injection on the n-sphere R-n is a Mobius transformation if and only if it is non-degenerate. More general results for hyperplane-to-hyperplane maps are obtained. The key method is to establish a new version of the celebrated Pappas' Theorem. |
