Quid of the Jones polynomial A knot is a closed curve in 3d space. The basic problem in knot theory is to say whether two given knots can be deformed one into another. Knot invariants are efficient tools to answer …

les exposés du groupe de travail n'ont pas lieu en raison du grand nombre d'exposés du semestre Holomorphic Dynamics and Geometry of Surfaces (02/25 --> 06/25) https://indico.math.cnrs.fr/category/740/

The Ginzburg-Landau functional was originally proposed as a model for superconductivity in Euclidean domains. However, invariance with respect to gauge transformations - which is one of the most prominent features …

In two papers published in 1979, R. Bowen and C. Series defined a dynamical system from a Fuchsian group, acting on the hyperbolic plane . The dynamic is given by a map on which is, in particular, a discontinuous …

This work will focus on the modeling of extreme events (possibly attached with a non extremal quantity) over a continuous spatial domain. For instance one may be interested in modeling extreme wind speeds and the …
