La bio-inspiration marine : quelques exemples

Nadia Améziane, professeure du Muséum national d'Histoire naturelle, apporte dans cette vidéo des exemples de bio-inspiration marine. En s'appuyant sur différents organismes marins, elle met en évidence la diversité des applications de cette bio-inspiration dans des domaines comme la santé, l'architecture, l'ingénierie ou encore la chimie. Elle souligne la nécessité de lier ces recherches à l'enjeu de conservation de la biodiversité.

D. Tewodrose - Limits of Riemannian manifolds satisfying a uniform Kato condition

I will present a joint work with G. Carron and I. Mondello where we study Kato limit spaces. These are metric measure spaces obtained as Gromov-Hausdorff limits of smooth n-dimensional Riemannian manifolds with Ricci curvature satisfying a uniform Kato-type condition. In this context, strictly wider than the ones of Ricci limit spaces (where the Ricci curvature satisfies a uniform lower bound) and Lp-Ricci limit spaces (where the Ricci curvature is uniformly bounded in Lp for some p>n/2), we extend classical results of Cheeger, Colding and Naber, ...

J. Fine - Knots, minimal surfaces and J-holomorphic curves

I will describe work in progress, parts of which are joint with Marcelo Alves. Let L be a knot or link in the 3-sphere. I will explain how one can count minimal surfaces in hyperbolic 4-space which have ideal boundary equal to L, and in this way obtain a knot invariant. In other words the number of minimal surfaces doesn’t depend on the isotopy class of the link. These counts of minimal surfaces can be organised into a two-variable polynomial which is perhaps a known polynomial ...
