General Information

Williams College hosted a conference in ergodic theory, with an emphasis on nonsingular and infinite measure-preserving actions.

The organizers were Joe Auslander (University of Maryland, College Park) and Cesar Silva (Williams College).

Supported by an NSF conference grant, Williams College, and Williams College Hagey Family Chair.
