Factorization method for nonlinear evolution equations Factorization method for nonlinear evolution equations
Swapan K. Ghosh, Debabrata Pal, Aparna Saha +1
The traditional method of factorization can be used to obtain only the particular solutions of the Liénard type ordinary differential equations. We suggest a modification of the ap…
Evolution equations for pulse propagation in nonlinear media
Debabrata Pal, Amitava Choudhuri, B Talukdar
We show that the complex modified KdV (cmKdV) equation and generalized nonlinear Schrödinger (GNLS) equation belong to the Ablowitz, Kaup, Newell and Segur or so-called AKNS hierar…
Embedded soliton solutions : A variational study
Debabrata Pal, Sk. Golam Ali, B. Talukdar
We use a variational method to construct soliton solutions for systems characterized by opposing dispersion and competing nonlinearities at fundamental and second harmonics. We sho…
Embedded solitons in the third-order nonlinear Schrödinger equation
Debabrata Pal, Sk. Golam Ali, B. Talukdar
We derive a straightforward variational method to construct embedded soliton solutions of the third-order nonlinear Schödinger equation and analytically demonstrate that these soli…
