# Highlights

### The Lebesgue labex

- makes a world-class research

as testified by the number of articles published every year in the best international journals, or the IUF nominations - is attractive

as shown by the number of CNRS researchers who chose to come there, among all possible math departments in France - invests in master, PhD and post-doc formation

with grants at all levels, that have several times given rise to thesis awards - is dynamical

with every year the organization of thematic semesters, gathering several conferences or summer schools around one common topic - participates in the diffusion of mathematics

notably with the 5 minutes Lebesgue
