Juan Souto - Counting curves on surfaces
SOUTO CLéMENT Juan
An old theorem of Huber asserts that the number of closed geodesics of length at most L on a hyperbolic surface is asymptotic to $\frac{e^L}L$. However, things are less clear if one either fixes the
Daniel Ketover - Sharp entropy bounds of closed surfaces and min-max theory
KETOVER Daniel
In 2012, Colding-Ilmanen-Minicozzi-White conjectured that the entropy of any closed surface in R^3 is at least that of the self-shrinking two-sphere. I will explain joint work with X. Zhou where we
E. Floris - Birational geometry of foliations on surfaces (Part 1)
FLORIS Enrica
The goal of this minicourse is to introduce MMP for foliations on surfaces and to outline the classification of foliations on projective surfaces up to birational equivalence.

14. Le châtaignier, pays et terroirs européens Espagne, terre de châtaigniers
JIMENEZ Jean
L'Espagne, depuis l'époque romaine, a connu un développement de sa castanéiculture proche du modèle français. Aujourd'hui, sa production est supérieure à la production française en termes de volumes.
