Emergence of the Gambier equation in cosmology
D. Batic, P. Guha, A. Ghose Choudhury
We show how the Gambier equation arises in connection to Friedmann-Lema$\mbox{î}$tre-Robertson-Walker (FLRW) cosmology and a Dark Matter equation of state. Moreover, we provide a c…
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…
Relativistic formulation of curl force, relativistic Kapitza equation and trapping
Partha Guha, Sudip Garai
In this present communication the relativistic formulation of the curl forces with saddle potentials has been performed. In particular, we formulated the relativistic version of th…
Regularization of central forces with damping in two and three-dimensions
E. Harikumar, Suman Kumar Panja, Partha Guha
Regularization of damped motion under central forces in two and three-dimensions are investigated and equivalent, undamped systems are obtained. The dynamics of a particle moving i…
Integrable modulation, curl forces and parametric Kapitza equation with trapping and escaping
Partha Guha, Sudip Garai
In this present communication the integrable modulation problem has been applied to study parametric extension of the Kapitza rotating shaft problem, which is a protypical example…
-flows Generated by the Curl of a Vector Potential \& Maurer-Cartan Equations
Oğul Esen, Partha Guha, Hasan Gümral
We examine flows admitting vector identity for a multiplier and a potential field $\mathbf{…
