Models of materials physics constitute a classical motivation and field of application for nonlinear analysis. A central example of this interplay is the analysis of weakly differentiable manifold-valued maps. This …

As an example for a random walk in random environment, we study biased random walk for dynamical percolation on the d-dimensional lattice. We establish a law of large numbers and an invariance principle for this …

Invariants are essential for classifying mathematical objects up to a group of transformations. This talk will review several constructions of rational invariants where a section to the orbits is an essential …

In an origami construction, we start with an infinite sheet of paper that we can consider to be the complex plane, with two marked points on it: 0 and 1. Origami constructions consist simply of a series of folds in …

This talk focuses on symbolic integration of differential forms, with a particular emphasis on historical and modern developments, from Abel’s addition theorems for Abelian integrals to Zeilberger’s creative …

Soit $c$un nombre rationnel et soit le polynôme quadratique $\varphi_c(X)=X^2-c$. On s'intéresse aux points périodiques rationnels de $\varphi_c$. Plus précisément, on s'intéresse à l'une des conjectures de …
