Reading seminar in algebraic geometry
Spring 2014. Syzygies.

This semester the reading seminar will study syzygies. Roughly speaking, given an algebraic variety, its defining equations typically satisfy non-trivial relations, called syzygies. The interplay between the commutative algebra of syzygies and the geometric properties of the variety is a basic topic in algebraic geometry.

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 Mondays at 3:00PM-4:00PM in LGRT 1322.
