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…
Quadratically damped oscillators with non-linear restoring force
Ankan Pandey, A Ghose Choudhury, Partha Guha
In this paper we qualitatively analyse quadratically damped oscillators with non-linear restoring force. In particular, we obtain Hamiltonian structure and analytical form of the e…
Chiellini integrability condition, planar isochronous systems and Hamiltonian structures of Liénard equation
A. Ghose Choudhury, Partha Guha
Using a novel transformation involving the Jacobi Last Multiplier (JLM) we derive an old integrability criterion due to Chiellini for the Liénard equation. By combining the Chielli…
Regular and Singular Pulse and Front Solutions and Possible Isochronous Behavior in the Short-Pulse Equation: Phase-Plane, Multi-Infinite Series and Variational Approaches
G. Gambino, U. Tanriver, P. Guha +2
In this paper we employ three recent analytical approaches to investigate the possible classes of traveling wave solutions of some members of a family of so-called short-pulse equa…
