Gravity theory of the generalized mass to horizon entropy The Iyer Wald approach
Subhra Mondal, Amitava Choudhuri
In this letter, our aim is to study the gravitational origin of the \textit{generalized mass-to-horizon entropy} (GMHE), described by an entropic exponent index and a multiplic…
Travelling wave solutions of equations in the Burgers Hierarchy
Amitava Choudhuri, Modhan Mohan Panja, Supriya Chatterjee +1
We emphasize that construction of travelling wave solutions for partial differential equations is a problem of considerable interest and thus introduce a simple algebraic method to…
On the solution and Lagrangian representation of Duffing oscillator with damping
Amitava Choudhuri, Madan Mohan Panja, Benoy Talukdar
We construct the equation of Duffing oscillator in a dissipative medium using certain concepts from elementary mechanics. The Duffing equation (DE) without damping can be solved an…
On the symmetries of the modified Emden-type equation
Subhra Mondal, Amitava Choudhuri
For an autonomous system the symmetries of the Lagrangian are embedded in the symmetries of the differential equation. Recently, it has been found that the modified Emden-type equa…
