Introduction
This is the webpage for Cascade Student Geometry Seminar (CSGS). It is a weekly student seminar on geometry based in the Pacific Northwest. Currently, this seminar is organized by some graduate students from University of Oregon, Oregon State University, University of Washington and University of British Columbia. This page is maintained by Yongmin Park at University of Oregon. If you have any questions/comments, please reach out to the organizers of CSGS.
Currently, we take a break during summer, and we are going to be back at the beginning of September 2023. The seminar is provided through Zoom, and usually we meet in afternoon (Pacific Time). If you are interested in this seminar, you can also subscribe our mailing list through the following link.

Moreover, for some recordings of the talks may be available for people who cannot attend the seminar.
