Contribution of the course to learning outcomes in the Master in Mathematics programme. By the end of this activity, students will have made progress in: 

- Choose and use calculation tools to solve mathematical problems.

- Identify 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.

- Argue within the context of the axiomatic method.

- Construct and draw up a proof independently, clearly and rigorously.

- Recognise the key arguments and the structure of a proof.

- Evaluate the rigour of a mathematical or logical argument and identify any possible flaws in it.

- Distinguish between the intuition and the validity of a result and the different levels of rigorous understanding of this same result.

- Write a mathematical text according to the conventions of the discipline.

- Find sources in the mathematical literature and assess their relevance.

- Correctly locate an advanced mathematical text in relation to knowledge acquired.

- Ask relevant and lucid questions on an advanced mathematical topic in an independent manner.


Learning outcomes specific to the course. By the end of this activity, students will be able to: 

- State, prove and illustrate propositions concerning properties of solutions of partial differential equations, and also the existence and uniqueness of such solutions.

- Propose one or several strategies to establish the existence of solutions.

- Apply tools from real analysis to solve a problem.

- Manipulate notions from advanced analysis.

- Contextualize mathematical tools in their historical setting and understand how they evolved.


The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.
- Fundamental solution and representation formulas
- Pointwise and global properties of solutions
- Approximation properties
- Sobolev spaces
- Dirichlet principle
Teaching methods
Learning activities consist of lectures and practical exercises. The lectures focus on and explain the subject's topics, tools, techniques and methods. The supervised practical exercises allow students to become familiar with topics, tools, techniques and methods in the field. The practical exercise sessions aim to teach students how to choose and use methods in order to solve problems. Activities are held in presential sessions.
Evaluation methods
Learning will be assessed by means of an individual project, by tasks supplied during the semester and by a final examination. Questions in the final examination will ask students to:
- reproduce material, especially definitions, theorems, proofs and examples
- demonstrate a certain mastery of the available tools
- explain the limits of a method or a tool
Assessment will be on the basis of
- knowledge, understanding and application of the different mathematical objects and methods from the course
- precision of calculations
- rigour of arguments, proofs and reasons
- quality of presentation of answers
