This is a basic first course in algebraic geometry.
In contrast to most such accounts it studies abstract algebraic varieties, and
not just subvarieties of affine and projective space. This approach leads more
naturally into scheme theory while not ignoring the intuition provided by differential geometry.
Contents
- Preliminaries from commutative algebra
- Algebraic sets
- Affine algebraic varieties
- Local study
- Algebraic varieties
- Projective varieties
- Complete varieties
- Normal varieties; (Quasi-)finite maps; Zariski's main theorem
- Regular maps and their fibres
Solutions to the Exercises

Prerequisites
Some familiarity with the basic objects of algebra, namely, rings,
modules, fields, and so on, as usually covered in advanced
undergraduate or beginning graduate courses.
(Topics in) Algebraic Geometry
These chapters discuss a few more advanced topics. They can be read
in almost any order, except that some assume the first.
