Finiteness of Totally Magnetic Hypersurfaces

Abstract

By introducing a dynamical version of the second fundamental form, we generalize a recent result of Filip-Fisher-Lowe to the setting of magnetic systems. Namely, we show that a real-analytic negatively -curved magnetic system on a closed real-analytic manifold has only finitely many closed totally -magnetic hypersurfaces, unless the magnetic 2-form is trivial and the underlying metric is hyperbolic.
