    On the characterization of the Navier-Stokes flows with the power-like energy decay

  • Original language description

    We study the energy decay of the turbulent solutions to the Navier-Stokes equations in the whole three-dimensional space. We show as the main result that the solutions with the energy decreasing at the rate O(t−α),t→∞, α in [0,5/2] , are exactly characterized by their initial conditions belonging into the homogeneous Besov space dotB− α2,∞ . Similarly, for a solution u and p in [1,∞] the integral int∞0|t α/2u(t)|p1/t dt is finite if and only if the initial condition of u belongs to the homogeneous Besov space dotB− α2,p . For the case α in (5/2,9/2] we present analogical results for some subclasses of turbulent solutions.
