Lax representations with non-removable parameters and integrable hierarchies of PDEs via exotic cohomology of symmetry algebras

Oleg I. Morozov

This paper develops the technique of constructing Lax representations for PDEs via non-central extensions generated by non-triivial exotic 2-cocycles of their contact symmetry alge…

Nonlocal symmetries, conservation laws, and recursion operators of the Veronese web equation

I. S. Krasil'shchik, O. I. Morozov, P. Vojčák

We study the Veronese web equation and using its isospectral Lax pair construct two infinite series of nonlocal conservation laws. In t…
