Abstract: In the context of a general lattice $\Gamma$ in ${\mathbf R}^n$ and a strictly expanding map $M$ which preserves the lattice, we characterize all the wavelet families, all the MSF wavelets, all the multiwavelets associated with a Multiresolution Analysis (MRA) of multiplicity $d\ge 1,$ and all the scaling functions. Moreover, we give several examples: in particular, we construct a single, MRA and $C^\infty ({\mathbf R}^n)$ wavelet, which is nonseparable and with compactly supported Fourier transform.
