The prerequisite(s) for this Teaching Unit (Unité d’enseignement – UE) for the programmes/courses that offer this Teaching Unit are specified at the end of this sheet.
At the end of this learning unit, the student is able to :
Contribution of the course to learning outcomes in the Bachelor in Mathematics programme. By the end of this activity, students will have made progress in:
- Recognise and understand a basic foundation of mathematics. In particular:
-- Choose and use the basic tools of calculation to solve mathematical problems.
-- Recognise the fundamental concepts of important current mathematical theories.
-- Establish the main connections between these theories, analyse them and explain them through the use of examples.
- Identify, by use of the abstract and experimental approach specific to the exact sciences, the unifying features of different situations and experiments in mathematics or in closely related fields.
- Show evidence of abstract thinking and of a critical spirit. In particular:
-- Argue within the context of the axiomatic method.
-- Recognise the key arguments and the structure of a proof.
-- Construct and draw up a proof independently.
-- Distinguish between the intuition and the validity of a result and the different levels of rigorous understanding of this same result.
Learning outcomes specific to the course. By the end of this activity, students will be able to:

- Use the fundamental principles of the theory of analytic functions: identity theorem, principle of the isolated zeros, principle of analytic continuation and maximum modulus principle.
- Determine the isolated singular points of an analytic function, compute the Laurent expansion in the neighborhood of an isolated singular point.
- Master the residue calculus, its application to the calculation of definite integrals and the determination of the number of zeros and poles of a meromorphic function.

Due to the COVID-19 crisis, the information in this section is particularly likely to change.Learning activities consist of lectures and exercise sessions. The lectures aim to introduce fundamental concepts, to explain them by showing examples and by determining their results, to show their reciprocal connections and their connections with other courses in the programme for the Bachelor in Mathematics. The exercise sessions focus on constructing proofs, examining numerous examples and counter-examples, and mastering methods of calculation.
Due to the COVID-19 crisis, the information in this section is particularly likely to change.Final exam testing the understanding of the theory and the ability to solve problems. Part of the note will be based on the continuous evaluation during the quadrimester. This part of the evaluation will be taken into account at each session and it will not be possible to retake it.
