Lyapunov spectrum for affine iterated function systems on the plane
We will present the Lyapunov spectrum (both entropy and Hausdorff dimension) for strongly regular affine iterated function systems on the plane, satisfying the strong separation condition. The affine iterated function system on the plane is …

Singularity versus exact overlaps for self-similar measures
I will present a recent preprint by Károly Simon and Lajos Vágó entitled "Singularity versus exact overlaps for self-similar measures". The main goal of the paper is to give a negative answer to the following …

Polynomial perturbations of Liouville integrable planar systems
We present recent progress in investigation of a polynomial perturbations of Liouville integrable system. Iterated variation as well as fewnomials theory is used.

Non-autonomous exponential dynamics: topology and dimension
We will talk about two results in the dynamics of \lambda e^z, which may still be proved in the more general situation of non-autonomous systems (here it means that the parameter \lambda changes at every step). We will …

Constructing transcendental entire functions
In this talk we use a lemma of Clunie and Kovari to construct some examples of transcendental entire functions with specific properties of their maximum modulus. It is a very useful tool that allows us …

O naturze porządku - wprowadzenie do teorii Christophera Alexandera
Prezentacja prac architekta Christophera Alexandera które, chociaż powstały w obszarze architektury, mają znacznie szersze implikacje. Interesują się nimi informatycy, teoretycy (i praktycy) zarządzania, teoretycy systemów złożonych. Na prezentacji zostaną przedstawione tematy takie, jak: - żywe …

Henryk Żołądek (Uniwersytet Warszawski)
Invariants of group actions, dim/deg duality and normal forms of vector fields
In 1932 R. Wetzenbock proved that the ring of polynomial invariants of a linear vector field in C^k is finitely generated. The proof eventually boils down to its most difficult case, when the vector field …

Absolutely continuous invariant measures for random maps of the interval
During the talk I will discuss results on the existence of the absolutely continuous invariant measures for random maps of the interval, together with the properties of the corresponding Frobenius-Perron operator. I will present the …

A’Campo’s forests for the space of complex polynomials
A new cellulation for the space of complex, polynomials is given. Each polynomial is characterized by A’Campo's ``geometric pictures’’ which are bi-colored planar graphs. These A’Campo forests provide a semi-algebraic stratification for the space. The …
