If radiative and self-force effects are neglected, we find that feeding a test particle into a near-extremal Kerr- Newman-AdS black hole could lead to destroy their event horizon, giving rise to naked singularities. H...

In this paper, we find that under a diffeomorphic of nonlinear geodesic equations are concerned with light-like extremal surfaces in curved spaeetimes. It is interesting to transformation of variables, the light-like ...
