Trajectories for Sasakian magnetic fields on real hypersurfaces of type (B) in a complex hyperbolic space

摘要

On a real hypersurface in a K?hler manifold we can consider a natural closed 2-form associated with the almost contact metric structure induced by K?hler structure. We treat trajectories under magnetic fields which are constant multiples of this 2-form. We consider a condition for them to be also curves of order 2 on tubes around totally geodesic real hyperbolic spaces in a complex hyperbolic space.
