# Baran H., Krasil'shchik I.S., Morozov O.I., and Vojcak P. Nonlocal symmetries of the 3D rdDym equation, talk at The Workshop on Integrable Nonlinear Equations, 18-24 October 2015, Mikulov, Czech Republic (abstract)

**Speaker**: Joseph Krasil'shchik

**Title**: Nonlocal symmetries of the 3D rdDym equation
**Abstract**:

Using Lax representation with non-removable parameter, we construct two infinite hierarchies of nonlocal conservation laws for the 3D rdDym equation and completely describe the algebras of nonlocal symmetries in the corresponding coverings.

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