- Representations attached to a given Cartan and infinitesimal character/differential: all_parameters_Cartan_gamma; all_parameters.
- Slides on K\G/B parameters: (x,lambda,nu). Case: G has discrete series = distinguished involution is I.
- Slides, continued: Finiteness of K\G/B. Parameter set for K\G/B.
- Slides, continued: SL(2,R) example.
- Slides, continued: Summary, fixing H,B and varying theta. Equivalent (\frak g,K_x)-modules.
- Slides, continued: More about KGB: Weyl groups, involutions, KGB space for SP(4,R).
