Generalised (2+1)-Dimensional Super MKdV Hierarchy for Integrable Systems in Soliton Theory

Much attention has been given to constructing Lie and Lie superalgebra for integrable systems in soliton theory, which often have significant scientific applications. However, this has mostly been confined to (1+1)-dimensional integrable systems, and there has been very little work on (2+1)-dimensional integrable systems. In this article, we construct a class of generalised Lie superalgebra that differs from more common Lie superalgebra to generate a (2+1)-dimensional super modified Korteweg-de Vries (mKdV) hierarchy, via a generalised Tu scheme based on the Lax pair method where the Hamiltonian structure derives from a generalised supertrace identity. We also obtain some solutions of the (2+1)-dimensional mKdV equation using the $G′/G^{2}$ method.

Soliton fission and fusion of a new two-component Korteweg-de Vries (KdV) equation

In this paper, the Painlevé test is performed for a new two-component Korteweg-de Vries (KdV) equation proposed by Foursov. It is shown that this equation passes the integrability test and is P-integrable. By means of the truncated singular expansion, some explicit solutions from the trivial zero solution are derived. The phenomena of soliton fission and fusion are studied in detail.     

Some new solitonary solutions of the modified Benjamin-Bona-Mahony equation

In this paper, we use the exp-function method to construct some new soliton solutions of the Benjamin-Bona-Mahony and modified Benjamin-Bona-Mahony equations. These equations have important and fundamental applications in mathematical physics and engineering sciences. The exp-function method is used to find the soliton solution of a wide class of nonlinear evolution equations with symbolic computation. This method provides the concise and straightforward solution in a very easier way. The results obtained in this paper can be viewed as a refinement and improvement of the previously known results.     

Soliton solutions of BLMP equation by Lie symmetry approach

Shallow water wave equations are usually described by Korteweg–de Vries (KdV)-type equations. In this paper, we have used Lie transformation group theory to solve (2+1)-dimensional Boiti–Leon–Manna–Pempinelli (BLMP) equation. We have obtained some exact solutions of BLMP equation in the explicit form through similarity reduction. All the reported results are expressed in closed form and analysed physically through their evolution profiles. The physical analysis reveals that the nature of solutions is parabolic, quasi-periodic, multisoliton and asymptotic.
