# Differential Geometry/PDE Seminar

The UW Differential Geometry / Partial Differential Equations (DG/PDE) Seminar is held in Padelford C-38 on Wednesdays 4:00 p.m. unless otherwise noted.

## Taking the DG/PDE Seminar for Credit

The Differential Geometry/PDE Seminar can be taken for graduate credit as Math 550A. You may obtain one credit by attending and participating in all but two of the seminar meetings, or two credits for giving a talk in the seminar. If you have any questions about these requirements, feel free to contact Yu YUAN.

## Seminar Mailing List

Announcements of upcoming DG/PDE seminars are sent by e-mail to all interested participants. To be added to (or removed from) the DG/PDE seminar mailing list, send e-mail to Yu YUAN.
