hyperbolic periodic point造句

1. If p is a hyperbolic periodic point, the stable manifold theorem assures that for some neighborhood U of p, the local stable and unstable sets are \ mathcal { C } ^ k embedded disks, whose tangent spaces at p are E ^ s and E ^ u ( the stable and unstable spaces of Df ( p ) ), respectively; moreover, they vary continuously ( in a certain sense ) in a neighborhood of f in the \ mathcal { C } ^ k topology of \ mathrm { Diff } ^ k ( X ) ( the space of all \ mathcal { C } ^ k diffeomorphisms from X to itself ).
