There are plenty of methods to discern order from chaos and to measure the magnitude of chaos in the framework of classical mechanics. Some of the methods are in the form of indices. First, we are going to discuss how we can reformulate these indices in the framework of general relativity in order to make them invariant under coordinate transformation. Then, we are going to show some interesting aspects of chaos detection methods when we study a test particle moving in the spacetime background of a black hole candidate.
