We prove that if the Hofer's symplectic energy of the Hamiltonian diffeomorphism is less than a topology number defined by the Lagrangian submanifold, then the Arnold conjecture is true in the degenerated (non-transversal) case.18 pages, submittedSymplectic Geometry58F05;58E05; 34C25; 58F10Cup-length estimate for Lagrangian intersectionstext
