Three uncertainty principles for an abelian locally compact group. Lectures given at the workshop ”Representation Theory of Lie Groups

The purpose of this article is to direct reader’s attention to some recent de-velopments concerning three Uncertainty Principles: the classical Heisenberg-Weyl Uncertainty Principle, The Hirschman-Beckner Uncertainty Principle based on the notion of the entropy, and the Donoho-Stark Uncertainty Principle. We state al
