%0 Journal Article %A Boscaggin, Alberto %A Dambrosio, Walter %A Muñoz Hernández, Eduardo %T A Maupertuis-type principle in relativistic mechanics and applications %D 2023 %@ 0944-2669 %U https://hdl.handle.net/20.500.14352/93475 %X We provide a Maupertuis-type principle for the following system of ODE, of interest in special relativity: d/dt (mx˙/√1 −|˙x|2/c2) = ∇V(x), x ∈ ⊂ Rn, where m, c > 0 and V : → R is a function of class C1. As an application, we prove the existence of multiple periodic solutions with prescribed energy for a relativistic N-centre type problem in the plane. %~
