Content

We plan to cover some of the core topics concerning algebraic varieties over an algebraically closed field and then some additional ones, depending upon the pace to which the course settles.

The core topics include affine and projective varieties, morphisms between them, basic properties of such (irreducibility, dimension, finiteness, degree, ...), sheaves, schemes, and the functor of points perspective, some key geometric notions and constructions (birational maps, blowups, projections, divisors, ...), some key examples (Segre, Veronese, Grassmannian, ...), properties of images of morphisms (Chevalley's theorem, universal closedness of projective varieties, ...), differential notions (tangent space, smoothness, ...).

For the additional topics, I have in mind the motivating goal of developing the basic theory of curves and surfaces (particularly intersection theory on the latter) to the extent required to present in the final lectures Weil's proof of the Riemann hypothesis for curves over finite fields.

Prerequisites

A course in commutative algebra is an official prerequisite, and it will certainly be helpful if you have (for instance) read

and done many of the exercises, but should not be necessary for general comprehension if you are willing to accept certain facts as black boxes.
