The Weitzenbock theorem about invariants
This theorem from 1932 says that the ring of polynomial first integrals of a linear vector field is finitely generated. I will present a new constructive proof of this result.

Orthogonal groups and periodicity of links
We study cyclic subgroups of orthogonal groups over Z_p and Z_{p^k}. We show what is the maximal r such that Z_{q^r} is a subgroup of the given orthogonal group. We apply this to obtain a …

Fast Birkhoff sums in expanding interval maps with infinitely many branches
We investigate expanding maps on the interval $[0,1]$ with the following properties: - infinitely many branches, image of each covering the whole $[0,1]$ (that is, $(0,1) = \bigcup I_i$ and $f(I_i)=[0,1] \forall i$), - uniformly …

Dimension of fast and slow escaping set
We study the dimension of sets of points in the Julia sets of entire transcendental functions which escape to infinity in a fast or slow way.

Variational principle for metric mean dimension
I will present results from a recent paper "From Rate Distortion Theory to Metric Mean Dimension: Variational Principle" by E. Lindenstrauss and M. Tsukamoto, were the variational principle for metric mean dimension is provided in …

Topological properties of generic homoclinic classes
The study of the dynamics of chain recurrence classes and their interaction with other chain recurrence classes has become a major problem in C1-generic dynamics. In particular, this has raised interest in the study of …

Simple proof of the uniformization theorem
I will present elementary proof of the uniformization theorem that any conformal structure in dimension two can be uniformized. This is Bojarski Ahlfors-Bers theorem.
