@article{Chanda2017DynamicalSO, title={Dynamical systems of null geodesics and solutions of Tomimatsu-Sato 2}, author={Sumanto Chanda and Partha Guha}, journal={arXiv: General Physics}, year={2017} }

We have studied optical metrics via null geodesics and optical-mechanical formulation of classical mechanics, and described the geometry and optics of mechanical systems with drag dependent quadratically on velocity. Then we studied null geodesics as a central force system, deduced the related Binet's equation applied the analysis to other solutions of Einstein's equations in spherically symmetric spaces, paying special attention to the Tomimatsu-Sato metric. Finally, we examined the dualities…
