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 …

Krzysztof Barański (Uniwersytet Warszawski)
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 …

Symetrie infinitezymalne specjalnych multi-flag redukują problem lokalnej klasyfikacji do algebry liniowej
W preprincie P. Mormul, F. Pelletier; Special 2-flags in lengths not exceeding four: a study in strong nilpotency of distributions; arXiv:1011.1763 [math.DG] (2010) podana była pełna klasyfikacja lokalna dla długości <= 4. Przy długości 4 …

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.
