摘要: Extending a result due to E. Zehnder [27], we prove that generically, an area-preserving analytic diffeomorphism of the plane has transversal homoclinic orbits and nondegenerate Mather sets in every neighborhood stable elliptic fixed point. “Generically” refers topology defined by means Taylor coefficients mapping at point whose order is higher than prescribed arbitrary integer, all lower being held fixed. The proof makes use Aubry-Mather theory for monotone twist mappings.
