Inclination-flip homoclinic orbits arising from orbit-flip

sigma egenerated homoclinic orbits for C-1 hows on closed 3-manifolds are s tudied. We assume that Gamma, the homoclinic orbit, is associated with a si ngularity sigma with real eigenvalues lambda (2) < <lambda>(3) < 0 < lambda (1). Degenerated means that either the centre-unstable and stable manifold s of sigma are tangent along Gamma (inclination-flip) or Gamma belongs to t he strong stable manifold of sigma (orbit-flip). We prove that if Gamma is orbit-flip, and -lambda (2) < <lambda>(1), then the corresponding vector he ld can be C-1 approximated by those exhibiting inclination-flip homoclinic orbits.
