Group analysis of a hyperbolic Lane-Emden system
(Elsevier, 2017)In this paper we carry out a complete Noether and Lie group classification of the radial form of a coupled system of hyperbolic equations. From the Noether symmetries we establish the corresponding conserved vectors. We ... -
Noether symmetries and exact solutions of an Euler-Bernoulli beam model
(World Scientific Publishing, 2016)In this paper, a Noether symmetry analysis is carried out for an Euler-Bernoulli beam equation via the standard Lagrangian of its reduced scalar second-order equation which arises from the standard Lagrangian of the ... -
Rosenau-KdV equation coupling with the Rosenau-RLW equation: conservation laws and exact solutions
(De Gruyter, 2017)We compute the conservation laws for the Rosenau-Kortweg de Vries equation coupling with the Regularized Long-Wave equation using Noether's approach through a remarkable method of increasing the order of the Rosenau-KdV-RLW ... -
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 ...
