Abstract : The Littlewood-Paley decomposition for functions defined on the whole space R^d and related Besov space techniques have become indispensable tools in the study of many partial differential equations. We recently developed parallel tools for the periodic domain T^d. Taking advantage of the boundedness and convergence theory on the square-cutoff Fourier partial sum,we define the Littlewood-Paley decomposition for periodic functions via the square cutoff. As an application of the tools developed here, we study the periodic weak solutions of the d-dimensional Boussinesq equations with the fractional dissipation (-/Delta)^/alpha u and without thermal diffusion.
