Abstract

We give a complete analysis of the projective unitary irreducible representations of the Poincaré group in 1+2 dimensions applying Mackey theorem and using an explicit formula for the universal covering group of the Lorentz group in 1+2 dimensions. We provide explicit formulae for all representations.
