We consider a family of transforms which are generalizations of the Fourier transform on abelian groups. When the group under consideration is 7/, members of this family are characterized by having a matrix whose i,jth element is a(/j mod n), where a is any given vector. We address the problem of when the inverse of a member of the family belongs to the family.

Experimental set up for the FT-rheology experiments. The strain, torque and normal forces are digitized via a stand-alone PC and monitored in parallel via an oscilloscope. The rheometer is controlled via a second PC that allows to measure linear mechanical properties via the commercial software.
Fourier transform spectroscopy is a technique that uses interference of light rather than dispersion to measure the spectrum of a substance. The basis of this technique is the Fourier-pair relationship between the interferogram (interference function) of a substance and its spectrum. This relationsh
