Abstract

We present a geometric characterization of the nonlinear smooth functions V:RRV: R\to R for which the origin is a global isochronous center for the scalar equation x¨=V(x)\ddot x=-V'(x). We revisit Stillinger and Dorignac isochronous potentials VV and show a new simple explicit family. Implicit examples are easily produced.
