Bilinearization of Supersymmetric KP Hierarchies Associated with Non-Trivial Flows
Sasanka Ghosh, Debojit Sarma
We show that the supersymmetric KdV and KP equations, related to the non-trivial flows, can be cast in the Hirota bilinear form. The existence of one, two and subsequently -soli…
A New Class of Optical Solitons
Sasanka Ghosh, Sudipta Nandy
Existence of a new class of soliton solutions is shown for higher order nonlinear Schrodinger equation, describing thrid order dispersion, Kerr effect and stimulated Raman scatteri…
Optical solitons in higher order nonlinear Schrodinger equation
Sasanka Ghosh, Sudipta Nandy
We show the complete integrability and the existence of optical solitons of higher order nonlinear Schrodinger equation by inverse scattering method for a wide range of values of c…
KDV Hierarchy and its Nonpolynomial Realization Through Kac-Moody Currents
Sasanka Ghosh, Samir K. Paul
It is shown that KdV hierarchy can be expressed as definite nonpolynomials in Kac Moody currents and their derivatives by the action of Borel subgroup of on the…
