Benjamin–Bona–Mahony equation with variable coefficients:conservation laws
(MDPI, 2014)This paper aims to construct conservation laws for a Benjamin–Bona–Mahony equation with variable coefficients, which is a third-order partial differential equation. This equation does not have a Lagrangian and so we transform ... -
Reductions and exact solutions of the (2+1)-dimensional breaking soliton equation via conservation laws
(Springer, 2017)We construct conservation laws for the (2 + 1)-dimensional breaking soliton equation. Thereafter, we employ the definition of the association of symmetries with conservation laws to obtain exact solutions for the (2 + ... -
Symmetry analysis and conservation laws for a coupled (2 + 1)-dimensional hyperbolic system
(Elsevier, 2015)This paper aims to perform Lie symmetry analysis and Noether symmetry classification of a coupled (2 + 1)-dimensional hyperbolic system. In the Lie analysis, the principal Lie algebra which is six dimensional extends in ... -
Variational approach and exact solutions for a generalized coupled Zakharov-Kuznetsov system
(Elsevier, 2017)In the present paper, we obtain a variational principle for a generalized coupled Zakharov-Kuznetsov system, which does not admit any Lagrangian formulation in its present form. The eminent Noether's theorem will then be ... -
A variational formulation approach to a generalized coulped inhomogenous emden–flowler system
(Taylor & Francis, 2014)We study a generalized coupled inhomogeneous Emden–Fowler system from the Lagrangian formulation standpoint. A special case of this system was considered in the literature, and necessary and sufficient conditions for the ...
