(Basic First Course in) Algebraic Geometry
pdf file for the current version (6.00)
These notes are an introduction to the theory of
algebraic varieties emphasizing the similarities to the theory of manifolds.
In contrast to most such accounts they study abstract algebraic varieties, and
not just subvarieties of affine and projective space. This approach leads more
naturally into scheme theory.
Contents
 Preliminaries from commutative algebra
 Algebraic sets
 Affine algebraic varieties
 Local study
 Algebraic varieties

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.
The files dated July 8 or 9, 2015,
