There are higher dimensional analogues to wavelet sets in , corresponding to wavelets in higher dimensions. Wavelet sets can be used to derive wavelets— by creating a set satisfying the conditions given above, and using the inverse Fourier transform on , you are guaranteed to recover a wavelet. A particularly interesting open question is: do all wavelets contain wavelet sets in their frequency support?
