Overview of course

This course is a second course in algebraic geometry. The prerequisites are a basic knowledge of algebraic geometry and commutative algebra. Some prior experience with sheaf cohomology would be useful but not essential. We will study complex algebraic surfaces, introducing the main computational tools of algebraic geometry along the way. Complex surfaces play a central role in algebraic, differential, and symplectic geometry, and number theory.

Tentative syllabus:

0. Topology of algebraic surfaces. Hodge theory.
1. Sheaves and cohomology.
2. Line bundles, divisors, morphisms to projective space.
3. Birational geometry of surfaces.
4. Characterization of the projective plane. del Pezzo surfaces.
5. Ruled surfaces.
6. K3 surfaces.
7. Elliptic fibrations.
8. Surfaces of general type.
