Fourier-Taylor approximation of unstable manifolds for compact maps: numerical implementation and computer-aided error bounds. -Taylor parameterization of unstable manifolds for parabolic partial di↵erential equations: Formalism, implementation and rigorous proof. If P is a conjugate covering map in the sense of Definition B.4, then the image of P is an unstable local manifold for .
A computationally convenient equivalent condition is given in the following proposition, which forms the core of the parameterization method for periodic orbits of differential equations. The proof for the case of finite dimensional vector fields is found in [11], and can be adapted to the present case of an unbounded ordinary differential equation defined densely on a Banach space. X is a conjugative covering map for a locally unstable manifold if and only if P satisfies the linear constraints of equation (42) and P solves the partial differential equation.
Note that this is exactly the same notion of non-resonance as occurs in the equilibrium case (see definition B.3), except with unstable eigenvalues replaced by unstable Floquet exponents.

Goodman, High-order adaptive method for computing two-dimensional invariant manifolds from three-dimensional maps, Commun. This suggests that the method could be useful in computer-aided existence proofing, a topic that will be the subject of future research.
Indeed, it seems possible to combine the techniques of [32] with the recent work of [20, 43] and the parameterization method of the present study to obtain computer-aided proofs of homoclinic and heteroclinic connection dynamics for infinite-dimensional systems. . Another interesting project would be to apply the methods of the present work to the difficult stable/unstable manifold calculations of the period five point discussed in [7]. Unfortunately, the explicit form of the map used for that study is not given in the reference (however, the authors note that the map is an 11th-order polynomial, a fact that suggests that the multiple-shooting approach of the present work can be a big help).
Another interesting direction of future research would be to apply rigorous globalization methods such as those of [66, 78] to grow the local manifolds studied here. This can lead to a better understanding of the connection pathway structure and topological entropy for discrete time systems. The authors would like to thank the three anonymous referees who read the submitted version of the manuscript for making a number of helpful suggestions.
