Course description

This is the first quarter of the introductory sequence in Algebraic Geometry. We will cover some of Chapters 1 and 2 of Hartshorne's book, as time permits. We will, in particular, define varieties and schemes and their basic properties.


MATH 200 A-B-C

There will be weekly homework assignments (posted below, but subject to change during the quarter). Please submit your homework online to Canvas as a pdf file by the due time and date. Late homework will not be accepted. Homework will normally be due one week after it is assigned, usually on a Tuesday. On the due date of a homework assignment, Canvas will automatically assign two of you as reviewers for each homework. The reviewers will write comments for the homework that they read. You will have two days, until the Thursday office hour, to read and comment on the homework that is assigned to you as reviewer. At the Thursday office hour, we will go over some of the solutions to the homework.
