NATAL

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 III.

Properties of Nonlinear Optical Crystals,The Bondi–Metzner–Sachs (BMS) group is an infinite-dimensional symmetry group of asymptotically flat gravity at null infinity, that extends Poincaré symmetry.

https://doi.org/10.1007/978-3-540-46793-9This chapter is devoted to irreducible unitary representations of the BMS. group, i.e. BMS. particles, which we classify and interpret. As we shall see, the classification is provided by supermomentum orbits that coincide with coadjoint orbits of the Virasoro group.
