Popis: It is established below that the existence of a strong solution to the nonlinear Navier–Stokes problem with any initial approximation from the class of strong solu� tions is equivalent to the global convergence of the modified iteration sequence to the sought solution in the norm of the class of strong solutions at a conver� gence rate higher than a geometric progression rate with a ratio arbitrarily close to zero. Interestingly, the sought strong solution is not involved in the construc� tion of the modified iteration sequence and, in fact, the global boundedness of this sequence in the norm of the class of strong solutions becomes a criterion for the global solvability of the nonlinear Navier–Stokes problem in the class of strong solutions (for more detail, see Section 2 below).
