The transversal homoclinic points are dense in the codimension-1 Henon-like strange attractors

We consider the codimension-1 Henon-like strange attractors Lambda. We prove that the transversal homoclinic points are dense in Lambda, and that hyperbolic periodic points are dense in Lambda. Moreover the hyperbolic periodic points that are heteroclinically related to the primary fixed point (transversal intersection of stable and unstable manifolds) are dense in Lambda.
