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

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