Description

The Monge-Ampère equation is a fully nonlinear elliptic equation, which plays a central role in geometry and in the theory of optimal transport. However, the singular and non-linear nature of the equation is a serious obstruction to its efficient numerical resolution. The first aim of the MAGA project is to study and to implement discretizations of optimal transport and Monge-Ampère equations which rely on tools from computational geometry (Laguerre diagrams). In a second step, these solvers will be applied to concrete problems from various fields involving optimal transport or Monge-Ampère equations such as

The MAGA project is funded by the French ANR for four years (2016—2020). The acronym MAGA stands for Monge-Ampère et Géométrie Algorithmique.


Laguerre diagram corresponding to the optimal transport between uniform measures over the unit ball and the so-called "tangle cube".
