Welcome to Math 248A: Algebraic Geometry

Algebraic geometry is the study of solutions of systems of polynomial equations. It is a classical field with a long history, which has a close relationship to many fields of pure math, but has also recently been applied to areas as diverse as engineering, computer graphics, cryptography, and algebraic statistics, to name a few. Because of the classical focus for 248A, I hope it will be accessible to a broad audience, including applied math students.


Lecture notes

I am attempting to put together self-contained notes for the course which could eventually replace Hartshorne. I will appreciate any feedback you can give me on them.

Lecture notes for the course.



Problem sets

Problem sets will be posted here on Wednesdays, due the following Wednesday in class. You are encouraged to collaborate with other students, as long as you do not simply copy their answers. Beyond this, you should not seek any external help.




Final Exam

There will be a takehome final exam for the course.
