serious and reasonably complete introduction to algebraic geometry, not just for
experts in the field. Topics covered includes: Sheaves, Schemes, Morphisms of
schemes, Useful classes of morphisms of schemes, Closed embeddings and related
notions, Fibered products of schemes, and base change, Geometric properties:
Dimension and smoothness, Quasicoherent sheaves, Quasicoherent sheaves on
projective A-schemes, Differentials,Derived functors, Power series and the
Theorem on Formal Functions, Proof of Serre duality.
This note contains the following subtopics of Algebraic Geometry,
Theory of Equations, Analytic Geometry, Affine Varieties and Hilbert’s
Nullstellensatz , Projective Varieties and Bezout’s Theorem, Epilogue
This book explains the following topics: Etale
Morphisms, Etale Fundamental Group, The Local Ring for the Etale Topology,
Sheaves for the Etale Topology, Direct and Inverse Images of Sheaves, Cohomology:
Definition and the Basic Properties, Cohomology of Curves, Cohomological
Dimension, Purity; the Gysin Sequence, The Proper Base Change Theorem,
Cohomology Groups with Compact Support, The Smooth Base Change Theorem, The
Comparison Theorem, The Kunneth Formula, Proof of the Weil Conjectures, The Weil
Conjectures, The Geometry of Lefschetz Pencils and Cohomology of Lefschetz

These notes are an introduction to the theory of algebraic varieties. 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.
