Construction of the classical time crystal Lagrangians from Sisyphus dynamics and duality description with the Liénard type equation
Partha Guha, A Ghose-Choudhury
We explore the connection between the equations describing Sisyphus dynamics and the generic Liénard type or Liénard equation from the viewpoint of branched Hamiltonians. The forme…
On Coupled Delayed Van der Pol-Duffing oscillators
Ankan Pandey, Mainak Mitra, A Ghose-Choudhury +1
We investigate the dynamics of a delay differential coupled Duffing-Van der Pol oscillator equation. Using the Lindstedt's method, we derive the in-phase mode solutions and then ob…
Reduction and Hamiltonian aspects of a model for virus-tumour interaction in oncolytic virotherapy
Anindya Ghose-Choudhury, Partha Guha
We analyse the Hamiltonian structure of a system of first-order ordinary differential equations used for modeling the interaction of an oncolytic virus with a tumour cell populatio…
On a geometric description of time dependent singular Lagrangians with applications to biological systems
Sudip Garai, A Ghose-Choudhury, Partha Guha
We consider certain analytical features of a stochastic model that can explain among other things competition among species and simultaneous predation on the competing species from…
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…
Nonlocal transformations of the Generalized Liénard type equations and dissipative Ermakov-Milne-Pinney systems
Partha Guha, A Ghose-Choudhury
We employ the method of nonlocal generalized Sundman transformations to formulate the linearization problem for equations of the generalized Liénard type and show that they may be…
