Induction is a technique yielding a large class of unitary representations of a given locally compact group G. It was used by Harish—Chandra in his theory of unitary representations of semisimple Lie groups. In my talk I will present the construction of representation of G which is induced from a representation of a closed subgroup H of G and discuss the main properties of the induction procedure. The example of the principal series of representations of SL(2,|C) will be presented. Then I will formulate the imprimitivity theorem characterising the class of induced representations of a given locally compact group and sketch its proof. The imprimitivity result will be linked with the Stone—von Neumann theorem and if time permits I will express the imprimitivity in terms of the Morita context assigned to a closed subgroup H of G. I will not say anything about the quantum version of the induction procedure which we are elaborating on with Kalantar, Skalski and Sołtan.
