WebT1 - The C1Closing Lemma, including Hamiltonians. AU - Pugh, Charles C. AU - Robinson, Clark. PY - 1983/6. Y1 - 1983/6. N2 - An Axiom of Lift for classes of dynamical systems is formulated. It is shown to imply the Closing Lemma. The Lift Axiom is then verified for dynamical systems ranging from C1diffeomorphisms to C1Hamiltonian vector fields.

When r = 0, this turns out to be trivial. When r == 1 it is proved in Refs. [7, 8, 9]. For r ^ 2, the C1' dosing lemma remains an open problem, even for flows on 2-manifolds. how to spell chisme
