Learning outcomes
At the end of this learning unit, the student is able to : | |
| 1 | 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: - Recognise the fundamental concepts of important current mathematical theories. - Establish the main connections between these theories, analyse them and explain them. - Recognise the fundamental concepts of important current mathematical theories. - Identify the unifying aspects of different situations and experiences. - Argue within the context of the axiomatic method. - Construct and draw up a proof independently, clearly and rigorously. - Write a mathematical text in French according to the conventions of the discipline. - Structure an oral presentation and adapt it to the listeners' level of understanding. - Find sources in the mathematical literature and assess their relevance. - Correctly locate an advanced mathematical text in relation to knowledge acquired. - Ask himself relevant and lucid questions on a mathematical topic in an independent manner. Learning outcomes specific to the course (en fonction des thèmes traités). Initiate to the current research in minima and critical points of integral functionals. - Start a research project with a deeper knowledge of an area of current mathematics. In particular, he will have developed his ability to: -- Independently develop mathematical intuition by anticipating expected results (formulating conjectures) and checking for consistency with already existing results. -- Independently ask relevant and lucid questions on an advanced mathematical topic. |
Content
The course will cover elements of Calculus of Variations in one variable :
- optimization problems;
- Euler-Lagrange equation;
- absolutely continuous functions and one-dimensional Sobolev spaces;
- not smooth extrema;
- Ekeland's variational principle;
- Mountain pass theorem.
Teaching methods
The learning activities consist of lectures and practical work sessions.
Lectures aim to introduce fundamental concepts, to motivate them by showing examples and establishing results, to show their reciprocal links and their links with other courses.
The practical work sessions aim to deepen the concepts covered during the lectures.
