Abstract: | Using the finite dimensional example of
, the universal covering of PSU(1,1), as a guide, we revisit the orbit method as it applies to
, the universal central extension of
. We clarify some aspects of the classification of coadjoint orbits, determine boundedness properties of the natural height function on these orbits, and calculate orbital integrals. |
