Remarks on the first integral method for solving nonlinear evolution equations

Aparna Saha, B. Talukdar Umapada Das, Supriya Chatterjee

We point out that use of the first integral method ( J.Phys. A :Math. Gen. 35 (2002) 343 ) for solving nonlinear evolution equations gives only particular solutions of equations th…

Solitons, compactons and undular bores in Benjamin-Bona-Mahony-like systems

Aparna Saha, B. Talukdar, Umapada Das +1

We examine the effect of dissipation on traveling waves in nonlinear dispersive systems modeled by Benjamin- Bona- Mahony (BBM)-like equations. In the absence of dissipation the BB…

Inverse variational problem for non-standard Lagrangians

Aparna Saha, B Talukdar

The non-standard Lagrangians (NSLs) for dissipative-like dynamical systems were introduced in an ad hoc fashion rather than being derived from the solution of the inverse problem o…

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…

On the non-standard Lagrangian equations

Aparna Saha, Benoy Talukdar

In an attempt to look for the root of nonstandard Lagrangians in the theories of the inverse variational problem we introduce a logarithmic Lagrangian (LL) in addition to the so-ca…
