Periodic solutions for a class of Lorenz-Lagrangian systems

Research output: Contribution to journalArticlepeer-review

Abstract

The class of Lorenz-Lagrangian systems under consideration are those of the form −Aq¨=∇V(q), q ∊ ℝn, where A is a real, symmetric matrix with eigenvalues µ1 < 0 < µ2 ≦ … ≦ µn, the corresponding eigenvectors being ei, 1 ≦ i ≦ n. If M+ and M are disjoint infinite submanifolds of ℝn which are the graphs of bounded real-valued functions on span {e2, …, en} with V = 0 on M+ ∪ M, V > 0 on the region Ω between M+ and M, and 〈∇V,e1〉≠0onℝn\Ω, then we show that there exists a periodic solution of this system, provided that ∇V points towards the e1 axis outside a large cylinder centred on the e1 axis.
