1. (mathematics) A theory for atomic decomposition of a range of Banach spaces of distributions, including among others the wavelet transform and the short-time Fourier transform.

     For Besov-Triebel-Lizorkin spaces, one uses a dyadic decomposition, while a uniform decomposition yields modulation spaces. Only recently, the second author has established a fruitful connection between modern variants of wavelet theory with respect to general dilation groups (which can be treated in the context of coorbit theory) and a particular family of decomposition spaces.
