Global surfaces of section in non-regular convex energy levels of Hamiltonian systems
The authors investigate the existence of global sections of disk-type in non-regular and strictly convex energy levels of integrable and near-integrable Hamitonian systems with two degrees of freedom based on the paper [\textit{H. Hofer, K. Wysocki} and \textit{E. Zehnder}, Ann. Math. (2) 148, No. 1, 197--289 (1998; Zbl 0944.37031)].
