Title
Order and chaos in a black hole magnetosphere

Abstract
While the motion of particles near a rotating, electrically neutral (Kerr) and a charged (Kerr-Newman) black hole is always regular, a perturbation to the gravitational or electromagnetic field generally leads to the presence of chaotic orbits. Transition from regular to chaotic dynamics is relatively gradual if the system preserves axial symmetry, whereas non-axisymmetry induces chaos more efficiently. In this contribution we study the development of chaos in an oblique (electro-vacuum) magnetosphere of a magnetized black hole.
