Semi-direct Productsunitary representations, which are induced from representations of their translation subgroup combined with a so-called .. We interpret these representations as . propagating in space-time and having definite transformation properties under the corresponding symmetry group. This picture will be inst

Coadjoint Orbits and Geometric Quantizationthe opposite phenomenon: starting from a . of a group ., we will obtain a representation by . the orbit. This construction will further explain why orbits of momenta classify representations of semi-direct products. In addition it will turn out to be a tool for understanding gravity in parts II and

Virasoro Coadjoint Orbitsal for our purposes because they will turn out to coincide with the supermomentum orbits that classify BMS. particles. As we shall see, despite being infinite-dimensional, these orbits behave very much like the finite-dimensional coadjoint orbits of ..
