AB - We study the Cauchy problem for the Korteweg–de-Vries equation in the class of functions approaching a finite- zone periodic solution of the KdV equation as $x → −∞$ and 0 as $x → +∞$. We prove the existence of infinitely many“regularized” integrals of motion for the solutions $u(x, t)$ of the Cauchy problem, with explicit dependence on time.
