Abstract: Topological classes are often invariant manifolds of renormalization. Unfortunately, renormalization is not a differentiable dynamical system. The stable manifold theorem for hyperbolic dynamics can not be applied. The talk will discuss a technique to construct smooth invariant manifolds in such a non-differentiable context.
