Title: Symmetries and conservation laws for a generalization of Kawahara equation

Abstract:
In this talk we study formal and generalized symmetries and local conservation laws for a fifth order nonlinear evolutionary partial differential equation in two independent and one dependent variable which generalizes the Kawahara equation. In particular, we establish nonexistence of formal symmetries of rank greater than 13 and give a complete description of generalized symmetries and local conservation laws for the equation under study.
