Coadjoint Orbits of the Poincar\'e Group in 2+1 Dimensions and their Coherent States
Abstract
We study the structure of the coadjoint orbits of the 2+1 Poincar\'e group, using a matricial representation of the group. We also obtain the orbits connected to irreducible representations of the group. Finally we obtain coherent states for the hyperboloidal and conical orbits.
