Descriptif
En partant des probabilités philosophiques de Cournot, et en étudiant l'accueil dans le monde scientifique de la notion de hasard chez Jacques Monod, ainsi que quelques cas de l'histoire de l'astronomie, nous nous sensibiliserons à la nature des risques que prend la construction de connaissance.Ceci nous permettra de pousser la réflexion épistémologique dans la ligne mais au delà de Thomas Kuhn et de Paul Feyerabend, dans le but premièrement d'un fonctionnement plus ouvert de la communauté scientifique, deuxièmement de prise en compte de problèmes environnementaux et écologiques mal appréhendés par la pensée économique.

J. Fine - Knots, minimal surfaces and J-holomorphic curvesFineJoël
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
-
D. Tewodrose - Limits of Riemannian manifolds satisfying a uniform Kato conditionTewodroseDavid
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

D. Stern - Harmonic map methods in spectral geometrySternDaniel
Over the last fifty years, the problem of finding sharp upper bounds for area-normalized Laplacian eigenvalues on closed surfaces has attracted the attention of many geometers, due in part to

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

J. Wang - Topological rigidity and positive scalar curvatureWangJian
In this talk, we shall describe some topological rigidity and its relationship with positive scalar curvature. Precisely, we will present a proof that a complete contractible 3-manifold with

P. Burkhardt - Pointwise lower scalar curvature bounds for C0 metrics via regularizing Ricci flowBurkhardt-GuimPaula
We propose a class of local definitions of weak lower scalar curvature bounds that is well defined for C0 metrics. We show the following: that our definitions are stable under greater-than-second
-
D. Semola - Boundary regularity and stability under lower Ricci boundsSemolaDaniele
The theory of non smooth spaces with lower Ricci Curvature bounds has undergone huge developments in the last thirty years. On the one hand the impetus came from Gromov’s precompactness theorem

C. Li - Classifying sufficiently connected PSC manifolds in 4 and 5 dimensionsLiChao
In this talk, I will discuss some recent developments on the topology of closed manifolds admitting Riemannian metrics of positive scalar curvature. In particular, we will prove if a closed PSC
-
A. Mondino - Time-like Ricci curvature bounds via optimal transportMondinoAndrea
The goal of the talk is to present a recent work in collaboration with Cavalletti (SISSA) on optimal transport in Lorentzian synthetic spaces. The aim is to set up a “Lorentzian analog” of the

Y. Lai - A family of 3d steady gradient Ricci solitons that are flying wingsLaiYi
We find a family of 3d steady gradient Ricci solitons that are flying wings. This verifies a conjecture by Hamilton. For a 3d flying wing, we show that the scalar curvature does not vanish at
