Fast Fourier Transforms for Symmetric Groups: Theory and Implementation
Recently, it has been proved that a Fourier transform for the symmetric group S„ based on Young's seminormal form can be evaluated in less than 0.5(h3 + n2)n\ arithmetic operations. We look at this algorithm in more detail and show that it allows an efficient software implementation using appropriate data structures. We also describe a similarly efficient algorithm for the inverse Fourier trans...
متن کاملGenerating fast Fourier transforms of solvable groups
This paper presents a new algorithm for constructing a complete list of pairwise inequivalent ordinary irreducible representations of a finite solvable group G. The input of the algorithm is a pc-presentation corresponding to a composition series refining a chief series of G. Modifying the Baum-Clausen-Algorithm for supersolvable groups and combining this with an idea of Plesken for constructin...

29 O(b log(b)) operations (using standard multiplication). As there are O(b= log(b)) primes in total, the running time of this stage of the algorithm is O(b 2 L), even using the \grammar school" method of integer multiplication. At this stage of the algorithm we have obtained a vector of length L whose entries are integral linear combinations of powers of with coeecients bounded by M in absolut...
متن کاملDimensionless Fast Fourier Transforms
This paper shows that there are fast Fourier transform (FFT) algorithms that work, for a fixed number of points, independent of the dimension. Changing the dimension is achieved by relabeling the input and the output and changing the “twiddle factors.” An important consequence of this result, is that a program designed to compute the 1-dimensional Fourier transform can be easily modified to com...
متن کاملFast algorithms for fractional Fourier transforms
The fractional Fourier transform (FRFT) is a one-parametric generalization of the classical Fourier transform. The FRFT was introduced in the 80th and has found a lot of applications and is now used widely in signal processing. Both the space and the spatial frequency domains, respectively, are special cases of the fractional Fourier domains. They correspond to the 0th and 1st fractional Fourie...
