The 24th Annual

Workshop in Geometric Topology

Calvin College, Grand Rapids, Michigan
June 28-30, 2007

Workshop Information

Ian Agol

Principal Speaker

The featured speaker is Ian Agol of the University of Illinois at Chicago and the University of California at Berkeley. He will give a series of three one-hour talks on the topology of 3-manifolds. The titles of the three talks are

  1. Finiteness of arithmetic hyperbolic reflection groups
  2. Survey on volumes of hyperbolic 3-manifolds
  3. Applications of Kleinian groups to 3-manifold topology

Contributed Talks

Participants are invited to contribute talks; time will be allotted each day for 20 minute talks by participants. In addition, there will be ample time set aside each day for informal discussions amongst participants.


Financial support, provided by the National Science Foundation, will be available to help defer the travel and living expenses of participants who do not have other funding for their research. Such support can be requested on the registration form. Graduate students and recent PhDs in geometric topology are especially encouraged to apply for support.
