Abstract:
In this paper, when the maximum time
Tv* is finite, the blow-up of the solutions to the fractional 3D incompressible Navier-Stokes equations in
Hs spaces and the decay in
L2 norm and the boundedness of the solution with respect to
H2-a norm,

norm and

norm are stud-ied, via using the property of Fourier transform, interpolation results and product law in the homo-geneous Sobolev spaces. It’s a generalization of the classical Navier-Stokes equations conclusion of Benameur J.
