Stable and unstable manifolds that are tangent to each other in a continuous dynamical system?

122 Views Asked by At

I am thinking of a scenario/ examples where the stable and unstable manifold of an equilibrium of a continuous dynamical system are tangent to each other?

Any examples/ plots would be helpful?

A straightforward example is a planar system with a homoclinic orbit, say \begin{align} \dot{x} = y,\\ \dot{y} = x - x^2. \end{align} The unstable and stable manifolds of the origin in the right half plane coincide, and hence are tangent.
