Study of a fifth order PDE using symmetries
Stylianos Dimas, Igor Leite Freire
We study a family of PDEs, which was derived as an approximation of an extended Lotka-Volterra system, from the point of view of symmetries. Also, by performing the self adjoint cl…
A generalised multicomponent system of Camassa-Holm-Novikov equations
Diego Catalano Ferraioli, Igor Leite Freire
In this paper we introduce a two-component system, depending on a parameter , which generalises the Camassa-Holm () and Novikov equations (). By investigating its Lie…
A family of wave equations with some remarkable properties
Priscila Leal da Silva, Igor Leite Freire, Júlio Cesar Santos Sampaio
We consider a family of homogeneous nonlinear dispersive equations with two arbitrary parameters. Conservation laws are established from the point symmetries and imply that the who…
