An
introduction to both the geometry and the arithmetic of abelian varieties. It
includes a discussion of the theorems of Honda and Tate concerning abelian
varieties over finite fields and the paper of Faltings in which he proves
Mordell's Conjecture. Warning: These notes are less polished than the others.
This course provides an introduction to the language of schemes,
properties of morphisms, and sheaf cohomology. Covered topics are: Basics of
category theory, Sheaves, Abelian sheaves, Schemes, Morphisms of schemes,
Sheaves of modules, More properties of morphisms, Projective morphisms,
Projective morphisms, Flat morphisms and descent, Differentials Divisors,
Divisors on curves, Homological algebra, Sheaf cohomology, Cohomology of
quasicoherent sheaves, Cohomology of projective spaces, Hilbert polynomials,
GAGA, Serre duality for projective space, Dualizing sheaves and RiemannRoch,
CohenMacaulay schemes and Serre duality, Higher RiemannRoch and Etale
cohomology.
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.
The material
presented here consists of a more or less self contained advanced course in
complex algebraic geometry presupposing only some familiarity with the theory of
algebraic curves or Riemann surfaces. But the goal, is to understand the
Enriques classification of surfaces from the point of view of Mori theory.
This is an introductory course note in algebraic geometry. Author has
trodden lightly through the theory and concentrated more on examples.Covered
topics are: Affine Geometry, Projective Geometry, The category of varieties,
Dimension theory and Differential calculus.
