Zermelo Wind: a geometrization of the frame dragging effect
Sumanto Chanda
In this article I discuss Zermelo's navigation problem in spacetime as a geometrization of the frame dragging effect, and recast various examples involving the latter into Zermelo…

Optical properties of null geodesics emerging from dynamical systems
D. Batic, S. Chanda, P. Guha
We study optical metrics via null geodesics as a central force system, deduce the related Binet equation and apply the analysis to certain solutions of Einstein's equations with an…

Jacobi-Maupertuis Randers-Finsler metric for curved spaces and the gravitational magnetoelectric effect
Sumanto Chanda, G. W. Gibbons, Partha Guha +2
In this paper we return to the subject of Jacobi metrics for timelike and null geodsics in stationary spactimes, correcting some previous misconceptions. We show that not only null…
