Course description

This is a first course in algebraic geometry. While there are no formal prerequisites beyond a knowledge of the material covered in the first-year algebra and geometry sequence, familiarity with some basic commutative algebra will be helpful. The rough outline of the course is as follows (subject to change):

• Affine and projective varieties.
• Morphisms and rational maps.
• Local properties: smoothness and dimension. Tangent space.
• Divisors.
• Low-dimensional varieties: curves and surfaces. Blow-ups.
• The Riemann-Roch Theorem.

Here is a more detailed lecture-by-lecture list of topics that I covered in the past, of course, this is all subject to change.

Handouts

• Correspondence between sets and ideals
• Proof of the Nullstellensatz

References

• Shafarevich, Basic Algebraic Geometry.
• Algebraic Geometry (online notes) by Milne.
• Hartshorne, Algebraic Geometry, Chapter I (this is more advanced, so does not quite match the content).
• Here is a discussion on MathOverflow with more books on algebraic geometry, but most of them are going to be too advanced.
• Here are notes from the last time I taught this course. These were taken in class, so

there are probably typos.
