L. Liechti - Minimal dilatations on nonorientable surfaces
...We discuss the problem of finding the minimal dilatation among pseudo-Anosov mapping classes ona fixed closed surface. In particular, for every nonorientable closed surface of even genus, we consider asimple candidate which conjecturally minimises... Voir la vidéo

Jeff Viaclovsky - Deformation theory of scalar-flat Kahler ALE surfaces
...I will discuss a Kuranishi-type theorem for deformations of complex structure on ALE Kahler surfaces, which will be used to prove that for any scalar-flat Kahler ALE surface, all small deformations of complex structure also admit scalar-flat Kahler... Voir la vidéo

Marie-José Bertin - Des nombres de Salem à la mesure de Mahler de surfaces K3 (Part 2)
...Le récent article de McMullen « Dynamics with small entropy on projective K3 surfaces » éclaire d’un jour nouveau les nombres de Salem. Ces entiers algébriques gardent cependant tout leur mystère. On peut tous les obtenir grâce à la... Voir la vidéo

Juan Souto - Counting curves on surfaces
...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 type of the curve, possibly changing the notion of... Voir la vidéo

Daniel Ketover - Sharp entropy bounds of closed surfaces and min-max theory
...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 interpret this conjecture as a parabolic version of... Voir la vidéo
