MAT 589: Introduction to Algebraic Geometry (Spring 2026)

About the course

In a nutshell, algebraic geometry studies systems of polynomial equations and the geometry of their solution sets. It is one of the oldest branches of mathematics, with many connections to other areas such as number theory, complex geometry, combinatorics, or theoretical physics.

The plan is to spend a few weeks on basic algebraic geometry (affine and projective varieties and their properties) and then to discuss more advanced topics (schemes and sheaves, cohomology, flatness, differentials). I plan to assign homework and provide written solutions for all the questions. If you are an undergraduate student taking this course, your grade will be determined by your homework and by a brief oral examination at the end of the semester.

Time and location

We meet on Monday and Wednesday, 9:30–10:50 am, in Math 4–130.

My office hours are Friday, 10am–1pm (or by appointment).
