Abstract

In this paper, we prove that if all closed characteristics on a compact non-degenerate star-shaped hypersurface Σ\Sigma in R2n\mathbf{R}^{2n} are elliptic, then either there exist exactly nn geometrically distinct closed characteristics, or there exist infinitely many geometrically distinct closed characteristics.
