What becomes of Fourier series and transforms when you abandon the familiar real line and circle group? It turns out that it is possible to define a notion of Fourier transform in the setting of a locally compact group of symmetries. There is a good Plancherel theory for some of these groups. Nearly every transform you have ever studied falls under the Fourier transfom on some Lie group: Laplace transforms, Bessel transforms, etc. and the familiar expansions in terms of exponential functions are replaced by expansions in other exotic special functions. The key to understanding all this is the study of representation theory for continuous groups. This also lies at the heart of the study of quantum mechanics, number theory and other arcane disciplines.
This is a huge subject, of which we can only see a fraction, but we will strive for some kind of overview. Techniques are used from algebra, topology, geometry, functional analysis and operator theory.
