In this note we show that the general theory of vector valued singular inte-gral operators of Calderón-Zygthmund defined on general metric measure spaces,can be applied to obtain Sobolev type regularity properties for solutions of the dyadic frac-tional Laplacian.In doing so,we define parhal derivatives in terms of Haar multipliers and dyadic homogeneous singular integral operators.
