The Workshops in Geometric Topology are a series of informal research conferences that have been held each year since 1984. Most have been partially supported by grants from the National Science Foundation. Previous workshops have been sponsored by Oregon State University, the Colorado College, Brigham Young University, Calvin College, the University of Wisconsin at Milwaukee, and Texas Christian University.
Each workshop features a series of three lectures by one principal speaker. This format allows the speaker to give a substantial introduction to an area of current research in geometric topology.
Participants are invited to contribute talks on their own research; time is allotted each day for short talks by participants. In addition, there is ample time set aside each day for informal interactions between participants.
All previous workshops are listed below. Click on recent locations to see the websites for those workshops.
