DESCRIPTION OF THE COURSE


Algebraic Geometry is the study of algebraic varieties, that is sets of common zeros of some polynomials. Historically this study is performed by the analysis of geometrical, algebraic, topological, differential, analytic and numerical properties. Such richness of points of view makes Algebraic Geometry one of the most fascinating and central areas of mathematics. Many famous problems in mathematics, like Fermat's Last Theorem, have been solved with the essential use of Algebraic Geometry.
The course introduces to basic properties of
affine and projective algebraic varieties, to maps among them, to their local geometry and to the theory of divisors and linear systems.

OUTLINE OF CONTENT

Affine spaces
Zariski topology. Affine closed subsets and radical ideals. Irreducible components. Regular functions and morphisms. Examples. Finite morphisms.
Varieties Projective spaces. Quasi-projective varieties. Projective hypersurfaces. Rational and regular functions. Morphisms. Affine varieties. Dimension. Generically finite morphisms. Constructible sets. Birational equivalence.
Geometry in projctive spaces Rational normal curves. Veronese varieties. Products. Projections. Invariance of projective closure. Complete intersections. Upper semicontinuity of dimension.

If there will be time, we will also do: local geometry, normalization; divisors, linear systems and associated morfisms.
