Algebraic Geometry Notes

This is a course in algebraic geometry. Actually, it is two courses, consisting of notes from a yearlong course that didn't get far enough (2002-03), and a quicker treatment from a course (in progress, Spring 2010) in which I am *determined* to get to the cohomology of coherent sheaves, as well as non-trivial properties of curves, surfaces and toric varieties. It is pre-Hartshorne, a cross between Mumford's Red Book (minus schemes) and Shafarevich's Basic Algebraic Geometry. My feeling is that by focusing on complex varieties, I am able to more clearly point out the relationship between commutative algebra and the geometry of varieties, and to get to properties of curves and surfaces without drowning the students in abstraction. Obviously, it would make better "Bourbaki" sense to start with Grothendieck's theory of schemes from the beginning, but it has been my experience that this approach (even in Mumford's Red Book) overwhelms all but the very best graduate students and results in an unsatisfying first-year course.
