When you do math in your everyday life, you expect there to be a correct answer to your calculations, but when you're dealing with infinity, you can't even assume that there even IS a correct answer. Mathematician W. Hugh Woodin has dedicated his life to problems that may not even have an

Abstract: The performance of numerical algorithms, both regarding stability and complexity, can be understood in a unified way in terms of condition numbers. This requires to identify the appropriate geometric settings and to characterize condition in geometric ways. A probabilistic analys

Maciej Zworski - From redshift effect to classical dynamics : microlocal proof of Smale's conjecture
Dynamical zeta functions of Selberg, Smale and Ruelle are analogous to the Riemann zeta function with the product over primes replaced by products over closed orbits of Anosov flows. In 1967 Smale conjectured that these zeta functions should be meromorphic but admitted "that a positive ans

The corner cube problem is interesting because it initially looks difficult. When the problem was first posed to me, for example, it didn't know how to solve it. Still, my intuition bells were ringing, telling me there was a nice solution. In this video, I cover two of these solutions, in

Gabriel Rivière: Correlation spectrum of Morse-Smale flows
Abstract: I will explain how one can get a complete description of the correlation spectrum of a Morse-Smale flow in terms of the Lyapunov exponents and of the periods of the flow. I will also discuss the relation of these results with differential topology. This a joint work with Nguyen V

R. Haslhofer - The moduli space of 2-convex embedded spheres
We investigate the topology of the space of smoothly embedded n-spheres in R^{n+1}, i.e. the quotient space M_n:=Emb(S^n,R^{n+1})/Diff(S^n). By Hatcher’s proof of the Smale conjecture, M_2 is contractible. This is a highly nontrivial theorem generalizing in particular the Schoenflies theor
