Preprint of the project: SFB 701: Spectral Structures and Topological Methods in Mathematics - Project A2Numerical analysis of high-dimensional transfer operators09-008 Fritz Colonius, Thorsten Hüls, Martin Rasmussen. We apply Newton's method in perturbed non-autonomous differential equations to determine heteroclinic connections which do not exist for the underlying unperturbed system. This approach is particularly useful in a higher dimensional context, where the numerical computation of invariant manifolds is very expensive. A detailed discussion of a four-dimensional model is presented, which describes a pendulum coupled to a harmonic oscillator.
