Piotr Mormul (Uniwersytet Warszawski)
Weak and strong nilpotentizability in the monster towers hosting flag distributions
Weak nilpotentizability (of a distribution = subbundle in the tangent bundle to a manifold) means the existence of a (local) nilpotent basis of sections. Strong nilpotentizability of a point, say p, is the equivalence of …

Dimension gap for self-affine sponges
I will describe recent results of D. Simmons and T. Das on the dimension of some class of self-affine sets and an example of an expanding repeller without ergodic invariant measure of full dimension.

Perturbations of the Lagrange and Hess-Appelrot cases in the rigid body dynamics
The Lagrange case in the rigid body dynamics is completely integrable, with a family of invariant tori supporting periodic or quasi-periodic motion. We study perturbations of this case. In the non-periodic case the KAM theory …

Maria das Neves Rebocho (Universidade da Beira Interior)
Discrete Painlevé equations for recurrence coefficients of Laguerre-Hahn orthogonal polynomials
Laguerre-Hahn orthogonal polynomials (LHOP) are related to Stieltjes functions that satisfy a Riccati differential equation with polynomial coefficients. Such families of orthogonal polynomials are very well-known in the literature of special functions and applications. They …

Shrinking target problem for Bedford-McMullen carpets
Given a dynamical system $T:X\to X$ with an ergodic invariant measure $\mu$, for any set $B, \mu(B)>0$ $\mu$-almost every trajectory will visit $B$ infinitely many times. However, it is an interesting question to ask a …

Marcin Bobieński (Uniwersytet Warszawski)
Bounds on multiplicity and noetherian intersections
We introduce the notion of a ring of Noetherian function that is finitely generated extension of polynomials. Some explicit upper bounds for the solutions of system of analytic equations can be deduced.

Wiener-Wintner theorem for semigroups of Markov operators
Topological version of the Wiener-Wintner theorem characterizes parameters z from the complex unit circle for which averages \frac{1}{N} \sum_{n=0}^{N-1} z^n f(T^n x) are uniformly convergent for every continuous function f, where (X,T) is a topological …
