Title: On nonlocal symmetries of the 3D rdDym equation

Abstract:

Using the Lax representation with non-removable parameter, we construct two hierarchies of nonlocal conservation laws for the 3D rdDym equation [math]\displaystyle{ u_{ty} = u_xu_{xy} - u_yu_{xx} }[/math] and describe the algebras of nonlocal symmetries in the corresponding coverings.

A joint work with H. Baran, O. Morozov, and P. Vojčák
