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 utu=uxuxy−uyuxx and completely describe the algebras of nonlocal symmetries in the corresponding coverings.

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