    A note on lower bounds of decay rates for solutions to the Navier-Stokes equations in the norms of Besov spaces

  • Original language description

    We study the lower bounds of decay rates for turbulent solutions to the Navier-Stokes equations in the norms of Besov spaces. We focus on solutions satisfying $0 < liminf_{t rightarrow infty} t^gamma ||u(t)|| le limsup_{t rightarrow infty} t^gamma ||u(t)|| < infty$ for some $gamma in (0,5/4]$ and prove among others that such solutions, measured in the norm of the Besov space $dot{B}^{-2gamma}_{2,infty}$, are estimated for large times from below by some positive constant. These estimates stem from sufficiently fast rate of large time energy concentration in low frequencies occurring in the studied solutions. Our results have simple proofs and improve and extend substantially the results published by Miyakawa in cite{Mi} and by Schonbek and Wiegner in cite{SchWi}
