Face-to-face or online courses are aimed at all levels up to bac +3. The course is structured as follows: - Explanation of the course - Methods/resolution of exercises - Report on the session and opening on a more complicated problem Of course, I am flexible on the organization of the course. It must above all meet the needs of the students. For online classes, I work with Zoom/Skype. In addition, the student can call me or send me a message outside of class if he has questions. The pleasure of working with you!
