### Content, Learning Outcome and Preconditions

#### Content

Part 1: set topology, topological spaces, metric spaces, neighbourhood bases, countability axioms, convergence, continuity, topological products, compact spaces, separation axioms, connected spaces, Theorem of Tychonov, paracompact spaces,
Part 2: fundamental group: paths, multiplication of paths, homotopy of paths, fundamental group, fundamental group of a circle, if time permits also: Brouwer Fixed Point Theorem, free groups, Theorem of Seifert and Van Kampen

#### Learning Outcome

At the end of the module, students are able to analyse topological spaces with regard to topological properties like connectedess and compactness. They are able to create bases and are able to make competent judgements about the fundamental groups of simple topological spaces.

#### Preconditions

Interested first-year students are welcome.
MA1001 (Analysis 1) , MA 1002 (Analysis 2), MA1101 (Linear Algebra and Discrete Structures 1), MA1102 (Linear Algebra and Discrete Structures 2)

### Courses, Learning and Teaching Methods and Literature

#### Courses and Schedule

VO 3 Topology Viehmann, E.
UE 1 Topology (Exercise Session) Viehmann, E.

#### Learning and Teaching Methods

lecture: oral presentation; exercise module: blackboard, oral presentation, group work
The module is offered as lectures with accompanying practice sessions. In the lectures, the contents will be presented in a talk with demonstrative examples, as well as through discussion with the students. The lectures should motivate the students to carry out their own analysis of the themes presented and to independently study the relevant literature. Corresponding to each lecture, practice sessions will be offered, in which exercise sheets and solutions will be available. In this way, students can deepen their understanding of the methods and concepts taught in the lectures and independently check their progress. At the beginning of the module, the practice sessions will be offered under guidance, but during the term the sessions will become more independent, and intensify learning individually as well as in small groups.

#### Literature

selected topics of: Jänich, Topologie, Bredon: Algebraic Topology, Hatcher: Algebraic Topology

### Module Exam

#### Description of exams and course work

The exam consists of one written exam (90 minutes) at the end of the semester. It tests if the students are able to reproduce and verify definitions and main assertions introduced in the lecture and to apply them to specific examples. In part of the questions, students will be asked for the final result of a calculation or to merely state a particular example, in others they have to present a shorter proof, a complete calculation, or a more involved example.

#### Exam Repetition

The exam may be repeated at the end of the semester.

#### Current exam dates

Currently TUMonline lists the following exam dates. In addition to the general information above please refer to the current information given during the course.
