  • New numerical schemes for extreme geophysical phenomena
    Sep 29, 2016 to Sep 30, 2016

    Final GeoNum Workshop

    New numerical schemes for extreme geophysical phenomena

    The GeoNum project aims at deriving high-order numerical methods to approximate nonlinear hyperbolic systems that arise when considering gravitational flows. The objectives are twofold. On the one hand, relevant models have to be carefully chosen in order to perform simulations of physical interest. Indeed, geophysical flows are generally modelled using Saint-Venant equations, which are not systematically well adapted to predict sophisticated shallow water flows. These models have to be extended to take into account important phenomena including turbulence, complex bathymetries or the sediments' impact on the topography's variation. On the other hand, the developments of new strategies to enforce highly accurate approximations required to simulate environmental flows are considered. Moreover, a particular attention must be paid on the robustness of the suggested algorithms. To address such an issue, classical schemes have to be extended into relevant high order approximations independently of both chosen topography and domain geometry. As a consequence, the resulting approaches are well adapted to perform real-life simulations.

  • Journée d'information et de réflexion sur l'édition scientifique
    Sep 29, 2016

    Cette journée a pour objectif d'informer les mathématicien-ne-s rennais-es sur le paysage de l'édition scientifique mathématique actuel et ses évolutions en cours. Elle ambitionne également de stimuler des comportements vertueux des individus et des structures en matière de publication d'articles et d'utilisation des ressources documentaires.

    Kähler geometry is a very active research field, at the crossroads between algebraic and Riemannian geometry. Important breakthrough, that lead to solve the Yau-Tian-Donaldson conjecture in the Fano case, have been achieved recently. A spring school involving mini-lectures and talks around this thread of new ideas in Kähler geometry is organized at Nantes University. The goal of the school is to develop certain technical skills, useful to address a variety of important questions in algebraic geometry and global analysis on manifolds, aimed for PhD students and young researchers. Geometric flows, like the Kähler-Ricci flow for instance, and the associated quantification by the Donaldson dynamical system, will be among the essential tools dealt with during the school.

Lebesgue Master Scholarship

lebesgue_money.png The Lebesgue Center offers 10,000€ scholarships to outstanding mathematics students applying for a master programme in mathematics, for a fist year of Master (M1) or for a second year of Master (M2), in Rennes, Nantes, Angers, Brest or Vannes.

Eligibility

The stipend is 10,000 euros per year.

The M1 scholarships are open to all students who have completed a bachelor's degree in mathematics (or related) at the end of the academic year 2015-2016. The applicants for the Lebesgue M1 scholarship should certify a B1 level of proficiency of the French language.
A student applying for the first year of a master (M1) will be allowed to apply for another scholarship for the second year (M2).

The M2 scholarships are open to all students who have completed the first year of a master in mathematics (or related) at the end of the academic year 2015-2016.
The courses of the second year of Master (M2) may be taught in English.

The application of the Lebesgue scholarship is independent from the application to Masters programmes, whom modalities are indicated in the dedicated websites.

Deadlines

The application for the lebesgue Master Scholarship is open until March 15th, 2016.
The results of the selection process will be edited in April 2016.

Contact

Applicants can obtain more information about the masters programmes on the page: Information.

Application

Applicants must complete the online form and attach the documents:
- CV
- Transcripts
- Cover letter
- One or more letters of recommendation.

Applicants must submit the application only when it is complete. Only electronic submission using the online form will be considered.

Selection

The selection will be carried out by the Lebesgue Scientific Committee and the heads of the Masters programmes. It will be based on the academic quality of the applicant.
