## Course description

## Objectives and Content

Objectives:

The course aims at giving an introduction to classical algebraic geometry, that is, the theory of algebraic varieties, and the most important notions and techinques to study these.

Contents:

The subject studies the Zariski topology and affine and projective varieties, as well as their regular functions, germs of regular functions, rational functions, dimension, Zariski tangent space and singularities. Moreover, also morphisms and rational maps between varieties and the differential of a morphism are studied, as well as simple intersection theory and Bezout's Theorem for curves in the projective plane. Some classical examples like products of varieties, blowing up of a point, the Segre embedding and the Veronese embedding are also presented*. *

## Learning Outcomes

On completion of the course the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge

The student

- is able to define and use fundamental notions and constructions and knows results in algebraic geometry connected to the Zariski topology, affine and projective varieties, their regular functions, rational functions, Zariski tangent space and singularities, as well as morphisms and rational maps between varieties
- is able to perform an elementary analysis of simple varieties, in particular answer questions on irreducible components and singularieties
- knows fundamental intersection theory and Bezout's theorem
