On purely nonlinear oscillators generalizing an isotonic potential
A. Ghose-Choudhury, Aritra Ghosh, Partha Guha +1
In this paper we consider a nonlinear generalization of the isotonic oscillator in the same spirit as one considers the generalization of the harmonic oscillator with a truly nonli…

Action-angle variables for the purely nonlinear oscillator
Aritra Ghosh, Chandrasekhar Bhamidipati
In this letter, we study the purely nonlinear oscillator by the method of action-angle variables of Hamiltonian systems. The frequency of the non-isochronous system is obtained, wh…
