Abstract
Let be an aspherical symplectic manifold, which is closed or convex. Let be an open set in , which admits a circle action generated by an autonomous Hamiltonian , such that each orbit of the circle action is not contractible in . Under these assumptions, we prove that the Hofer-Zehnder capacity of is bounded by the Hofer norm of . The proof uses a variant of the energy-capacity inequality, which is proved by the theory of action selectors.
