Learning unit contents

This course is an introduction to general topology.
The main purpose of general topology is the abstract definition and study of concepts such as continuity of mappings, connectedness, compactness ...
These concepts are usually defined in the first course in analysis for Euclidean spaces. They will be generalized for arbitrary sets.
For instance, the following topics could be presented :
The general definition of a topology, neighborhoods of points, interior, closure and boundary of a set.
We will study the continuity of mappings and define the initial and final topologies.
We will deal with subspaces, product spaces and quotient spaces.
The axioms of separation will be studied.
The last sections will be devoted to the definitions and properties of compact spaces and connected spaces.
A few classical theorems will also be presented.

Learning outcomes of the learning unit

At the end of the course, the students should be able to make a presentation of the theory or to use it in order to solve exercises
They should also be able to read the literature in order to make a report and a short talk about a topic proposed by the teacher.
This knowledge of general topology is useful for the students for lectures in advanced algebra, geometry and analysis. It should also help them to think of several difficult points they could have to teach in the secondary school.

Prerequisite knowledge and skills

A basic knowledge of naïve set theory, functions, Euclidean spaces and quotient spaces is assumed. A good knowledge of topological concepts (open sets connectedness compactness) in the Euclidean spaces is useful.

Planned learning activities and teaching methods

The theory is given mainly on the blackboard and is illustrated by simple examples whenever it is possible. Students are encouraged to ask questions and to participate.
During the exercise sessions, students are asked to solve exercises under the supervision of the teacher, who also gives a solution. When possible, a list of exercises will be given a few days before the exercise session, so that the student can prepare the exercises before the session.

Mode of delivery (face-to-face ; distance-learning)

Face-to-face
The schedule of the lectures is determined by the "conseil des études en mathématiques" and available on the website of the department of mathematics.

Assessment methods and criteria

A written examination of exercises will be organized.
There will also be an oral examination.
The students will be asked to develop two of the themes that were dealt with in the theoretical course.
The final result will be an arithmetic mean of the results obtained by the students for the two parts of the exam, if the grades for the two parts of the exams are greater or equal to 7/20. Otherwise, the final grade could be less than the arithmetic mean.

Work placement(s)

Organizational remarks

The exam should take place in January, as indicated above. However, this has to be confirmed by the "Conseil des études en Mathématiques". This council also determines the schedule of exams.
