Algebraic geometry II · Math 632
This is the second course in the algebraic geometry sequence. We will continue to study varieties, schemes, and coherent sheaves. A large portion of this course will focus on the development of sheaf cohomology -- especially the properties and computation of cohomology of coherent sheaves.

Algebraic geometry by Robin Hartshorne,
Foundations of Algebraic Geometry by Ravi Vakil.
Algebraic geometry II by David Mumford and Tadao Oda
We will use all the above texts in tandem. It is not too difficult to find pdfs online of these texts. For Hartshorne, it is possible to download the text through Springer using umich credentials. For Mumford and Oda, there is a penultimate draft available online.
Your grade will be determined as follows. Homework will count towards 50% of your grade, the midterm will count towards 20% of your grade, and the final exam will count towards 30% of your grade.
We will have homework due approximately every one to two weeks, handed in at the beginning of class. Homework will be posted on the course website with a pdf link by the date in the calendar that it is due.
