Introduction in Sheaves and Schemes

Teaching semester

Irregular. Typically the course will be offered in the same semester as MAT229

Objectives and Content

Objectives:

The course aims at giving a first introduction to sheaves and schemes in

algebraic geometry and their fundamental properties. This forms the

basis of modern algebraic geometry.

Contents:

The subject studies sheaves and morphisms between them,

especially short exact sequences, and definition and fundamental

properties of locally ringed spaces and schemes and morphisms between

schemes. In particular, the notions affine, noetherian, integral,

reduced, irreducible, separated, proper and projective schemes are

considered, as well as the structure sheaf, generic point, closed and

open embeddings, fiber product and fiber. The connection between schemes

and varieties is also studied.

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 important results in algebraic geometry connected to sheaves and

schemes

* is able to perform a simple analysis of schemes, in particular using

properties of well-known sheaves.

* is able to produce the main ideas in the proofs of the most important

results connected to the notions above.

Skills

The student

* masters fundamental techniques within sheaf and scheme theory

* is able to argue mathematically correct and present proofs and

reasoning

* has solid experience and training in reasoning with sheaves and

geometric stuctures

General competence

The student

* is able to work individually and in groups

* is able to formulate in a precise and scientifically correct way

* is able to decide whether complex mathematical arguments are correct
