#### Metrics, gerbes, and the genus expansion

###### Sheldon Katz   [email] (UIUC Math and Physics)

Abstract: Having described the closed string spectrum from a physical viewpoint (graviton, B-field, dilaton), we describe the geometry that this focuses attention on: metrics, connections on gerbes, and the genus expansion parameter.
