Functions on the sphere with critical points in pairs and orthogonal geodesic chords

R. Giambò, F. Giannoni, P. Piccione

Using an estimate on the number of critical points for a Morse-even function on the sphere $S^{m}$ , $m \geq 1$ , we prove a multiplicity result for orthogonal geodesic chords in…

Multiple brake orbits in $m$ -dimensional disks

R. Giambò, F. Giannoni, P. Piccione

Let $(M, g)$ be a (complete) Riemannian surface, and let $Ω \subset M$ be an open subset whose closure is homeomorphic to a disk. We prove that if $\partial Ω$ is smooth and it satisf…
