This chapter contains a local analysis of Q p(T) based on the dyadic portions. First of all, we give an alternate characterization of Q p in terms of the square mean oscillations over successive bipartitions of arcs in T. Next, we consider the dyadic counterpart Q p d(T) of Q p(T), in particular, we show that f ∈ Q p(T) if and only if (almost) all its translates belong to Q d p(T); conversely, functions in Q p(T) may be obtained by averaging translates of functions in Q p(T). Finally, as a natural application of the dyadic model of Q p(T), we present a wavelet expansion theorem of Q p(T).
