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

摘要:

研究了Veronese网方程$u_y u_{tx}+ λu_xu_{ty} - (λ+1)u_tu_{xy} =0$,利用它的等谱拉克斯对构造了两个非局部守恒律的无穷级数.在与这些级数相关的无穷微分覆盖中,我们描述了相应的非局部对称的李代数。最后,我们构造了一个递归算子,并探讨了它对非局部阴影的作用。操作符提供一个新的阴影,作为主对称。

英文摘要:

We study the Veronese web equation $u_y u_{tx}+ λu_xu_{ty} - (λ+1)u_tu_{xy} =0$ and using its isospectral Lax pair construct two infinite series of nonlocal conservation laws. In the infinite differential coverings associated to these series, we describe the Lie algebras of the corresponding nonlocal symmetries. Finally, we construct a recursion operator and explore its action on nonlocal shadows. The operator provides a new shadow which serves as a master-symmetry.
