On Geodesic Flows and Their Deformations in Bertrand Space-times    [PDF]

Prashant Kumar, Kaushik Bhattacharya, Tapobrata Sarkar

We study the energy conditions and geodesic equations of Bertrand space-times. We show that these can be thought of as interesting physical space-times in certain regions of the parameter space where the weak and strong energy conditions hold. We further compute the ESR parameters for a class of such space-times and analyze them numerically.
