The Cooley-Tukey FFT can be interpreted as an algorithm for the efficient computation of the Fourier transform for the finite cyclic groups, a compact group, or the non-compact group of the real line. All of which are commutative instances of a "Group FFT". A brief survey of some recent progress made in the direction of noncommutative generalizations and applications is given.

Decimation-in-Frequency Fast Fourier Transforms for the Symmetric Group
In this thesis, we present a new class of algorithms that determine fast Fourier transforms for a given finite group G. These algorithms use eigenspace projections determined by a chain of subgroups…
A Fast Fourier Transform for the Symmetric Group
A discrete Fourier transform, or DFT, is an isomorphism from a group algebra to a direct sum of matrix algebras. An algorithm that efficiently applies a DFT is called a fast Fourier transform, or…

Generalized FFTS - A Survey of Some Recent Results
TLDR
This paper surveys some recent work directed towards generalizing the fast Fourier transform (FFT) from the point of view of group representation theory, and discusses generalizations of the FFT to arbitrary finite groups and compact Lie groups.

The discrete Fourier transform of a sequence of N points, where N is a prime number, is shown to be essentially a circular correlation, which permits the discrete Fouriers transform to be computed by means of a fast Fouriertransform algorithm, with the associated increase in speed, even though N is prime.
