Fourier transformation is an invertible integral transformation that map [[piecewise continuous functions]] from one [[topological group]] to another such that the kernel of the transformation is a generator of the group.
Often, functions which are difficult to analyze in one topological group become much easier to analyze when transformed to another topological group.
