There are several ways of formulating the uncertainty principle for the Fourier transform on Rn. Roughly speaking, the uncertainty principle says that if a function f is concentrated then its Fourier transform f cannot be concentrated unless f is identically zero. Of course, in the above, we should be precise about what we mean by concentration. There are several ways of measuring concentration and depending on the definition we get a host of uncertainty pronciples. As several authors have shownc some of these uncertainty principles seem to be a general feature of harmonic analysis on connected locally compact groups. In this paper, we show how various uncertainty principles take form in the case of some locally compact groups including Rn, the heisenberg group, the reduced Heisenberg group and the Euclidean motion group of the plane.
