Solutions with minimal period for Hamiltonian systems in a potential well. (English) Zbl 0623.58013

Let \(U\in C^ 2(\Omega)\), where \(\Omega\) is a bounded set in \({\mathbb{R}}^ N\). Suppose that U(x) tends to \(+\infty\) as x tends to \(\partial \Omega\). Our main results concern the existence of periodic solutions of - ẍ\(=U'(x)\) having a prescribed number T as minimal period. The results are also generalized to first order Hamiltonian systems.
