## The positive energy models for the Virasoro algebra

##### Abstract:

The talk will describe old and new(er) results on the structure of modules for the Virasoro algebra. Joint work of Rocha and Goodman with the speaker will be the old work. A newer result to be is a description of the annihilators of Verma modules (analogous to Dixmier's result for semi-simple Lie algebras) and its relationship with Small's albatross.
