Symmetry properties of some Euler-type equations in plasma physics
F. Ceccherini, G. Cicogna, F. Pegoraro
We consider a system of partial differential equations, of interest to plasma physics, and provide all its Lie point symmetries, with their respective invariant solutions. We also…

On the relation between standard and -symmetries for PDEs
G. Cicogna. G. Gaeta, P. Morando
We give a geometrical interpretation of the notion of -prolongations of vector fields and of the related concept of -symmetry for partial differential equations (extending to…
