Reading seminar in algebraic geometry
Fall 2012. Deformation theory.

This semester the reading seminar will study deformation theory via key examples.

The seminar will consist of introductory talks by faculty followed by talks by graduate students. We will attempt to make the seminar accessible to everyone.

The seminar will meet on Fridays at 2:40PM-3:45PM in LGRT 1634.
