Streszczenie

We study the existence and regularity of invariant graphs for bundle maps (or bundle correspondences with generating bundle maps motivated by ill-posed differential equations) having some relative partial hyperbolicity on non-trivial and non-locally-compact bundles. The regularity includes (uniform) $ C^0 $ continuity, Hölder continuity and smoothness. To illustrate the power of our results and methods, a number of applications to both well-posed and ill-posed semilinear differential equations and abstract infinite-dimensional dynamical systems are given. These applications include the existence and regularity of different types of invariant foliations (laminations), including strong stable laminations and fake invariant foliations, the existence and regularity of holonomies for cocycles, the $ C^{k,\alpha} $ theorem and decoupling theorem, etc., in a general setting.
