Włosy dla hiperbolicznych funkcji całkowitych skończonego rzędu
Niech f będzie hiperboliczną funkcją całkowitą skończonego rzędu taką, że zbiór osobliwości f-1 jest ograniczony i f ma dokładnie jedną składową Fatou. Pokazujemy, że zbiór Julii funkcji f jest bukietem Cantora w sensie Aartsa-Oversteegena. Jest …

Transfinite Hausdorff Dimension
Making extensive use of small transfinite topological dimension trind, we ascribe to every metric space $X$ anordinal number (or $-1$ or $\Om$) $\tHD(X)$, and we call it the transfinite Hausdorff dimension of $X$. This ordinal …

Tomas Persson (Lund University)
Smooth Livšic regularity for piecewise expanding maps
We consider the regularity of measurable solutions $\chi$ to the cohomological equation \[ \phi = \chi \circ T -\chi, \] where $(T,X,\mu)$ is a dynamical system and $\phi \colon X\rightarrow \R$ is a $C^k$ valued …

Michael F. Barnsley (Australian National University)
The dynamics and an index for real projective iterated function systems
I will give a reasonably complete description of the dynamics associated with arbitrary real projective iterated function systems, including their Conley decomposition (which describes the attractor/repeller structure), and a beautiful duality result. Using these ideas, …

Galina Filipuk (Uniwersytet Warszawski)
On some properties of auxiliary functions associated to the Painleve equations $P_{II} - P_{V}$
Painleve equations are nonlinear second order ordinary differential equations, solutions of which have no movable critical points (i.e., solutions are meromorphic on the universal cover of P1-{several fixed singularities}). Painleve transcendents are regarded as nonlinear …

Random Quantum Maps and a quantum analogue of Frobenius-Perron theorem
Statistical properties of periodically driven quantum chaotic systems described in a finite dimensional Hilbert space can be mimicked by random unitary matrices distributed according to the Haar measure on the unitary group.To describe the effect …

Michał Szostakiewicz (Uniwersytet Warszawski)
On Lyapunov exponents of rational maps on P^k
Urbański and Zdunik have constructed and studied the equilibrium states for rational maps on complex projective spaces. In my talk I will explain how to prove that their Lyapunov exponents are positive. The main tool …

On some random fractals
I will present a simple method of calculating Hausdorff dimension of some random fractal sets.
