UE6. Numerical analysis - 4 ECTS -- 20h

(T. Champion) We are interested in numerical analysis of convex optimization problem (with or without constraint) in infinite dimension. Existence results are proposed as well as algorithms to solve such problems.

UE7. Seminar / Language - 6 ECTS

Student seminar - 2 ECTS

In this seminar, each student has to present to the class a little chapter, research article or modelization problem proposed by one of the teachers of the classes.

Scientific english - 3 ECTS -- 18h

This class will focus on oral and written comprehension/production of English with a strong emphasis on oral interaction. Students will be asked to do an oral presentation connected with their field of study; this presentation will lead to a debate in English between students. Additionally, we will work on other scientific themes, mainly through the prism of video and written documents. Students are required to attend class and to actively participate.

Technics for job search - 1 ECTS - 10h

Course under the responsability of Service d’Accompagnement en Orientation et Insertion (SAOI).

UE8. TER - 20 ECTS

The Master thesis has to be written within 4 months' time. You can choose your advisor from one of the two research labs CPT (located on the campus of La Garde and on the campus of Luminy inMarseille) and IMATH  (located on the campus of La Garde), or from an exterior company.

Remark UE8

This compulsory UE, typically divided into two parts, consists of 40 hours. According to the two thematic orientations Mathematical physics and Optimization and applied analysis, the corresponding lectures may be shared with the Master Theoretical and mathematical physics, particle physics, and astrophysics (P3TMA) of Aix Marseille University, with the Master Mathematics of AixMarseille University and the University of Nice, and with the school of engineering SeaTech, respectively.

Remark Master Thesis (UE9)

The Master thesis has to be written within 4 months time. You can choose your advisor from a research lab of a University, generally one of the two research labs CPT (located on the campus of La Garde and on the campus of Luminy inMarseille) and IMATH  (located on the campus of La Garde), or from an exterior company.
