The syllabus for Math 631 (Algebraic Geometry I) is available here.

The current office hours schedule is: Mon 2pm-3pm in EH 3842, Wed 8pm-9pm on Zoom (link in syllabus above), Thu 3pm-4pm in EH 3842.

We will be loosely following Ravi Vakil's notes Foundations of Algebraic Geometry.

As the semester progresses, I will post problem sets and a rough schedule of topics here. I've set up a basic Canvas site just for announcements (and possibly Gradescope).

Weekly problem sets will be posted here on Thursday afternoons. They will not count towards your grade in the course but you are still expected to think about them to follow along with the course material! Even though the problem sets will not count towards your grade, I highly encourage you to write down solutions to some or all of them and send them to me by e-mail (address in the linked syllabus above) for feedback. I am also happy to answer questions about specific problems by e-mail or in office hours.
