Abstract

We construct an infinite hierarchy of nonlocal conservation laws for the ABC equation \(A u_t\,u_{xy}+B u_x\,u_{ty}+C u_y\,u_{tx} = 0\), where ABC are nonzero constants and \(A+B+C\ne 0\), using a nonisospectral Lax pair. As a byproduct, we present new coverings for the equation in question. The method of proof of nontriviality of the conservation laws under study is quite general and can be applied to many other integrable multidimensional systems.
