Algebra Properties in Fourier-Besov Spaces and Their Applications

الملخص EN

We estimate the norm of the product of two scale functions in Fourier-Besov spaces.

As applications of these algebra properties, we establish the global well-posedness for small initial data and local well-posedness for large initial data of the generalized Navier-Stokes equations.

Particularly, we give a blow-up criterion of the solutions in Fourier-Besov spaces as well as a space analyticity of Gevrey regularity.
