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 ...

M. Lesourd - Positive Scalar Curvature on Noncompact Manifolds and the Positive Mass Theorem

The study of positive scalar curvature on noncompact manifolds has seen significant progress in the last few years. A major role has been played by Gromov's results and conjectures, and in particular the idea to use surfaces of prescribed mean curvature (as opposed to minimal surfaces). Having the classic positive mass theorem of Schoen-Yau in mind, we describe a new positive mass theorem for manifolds that allows for possibly non asymptotically flat ends, points of incompleteness, and regions negative scalar curvature. The proof is ...
