Title: On nonlocal symmetries of the 3D rdDym equation
Using the Lax representation with non-removable parameter, we construct two hierarchies of nonlocal conservation laws for the 3D rdDym equation and describe the algebras of nonlocal symmetries in the corresponding coverings.
A joint work with H. Baran, O. Morozov, and P. Vojčák
