Orbifold expansion and bounded Fatou components
The notion of expansion on its various forms is fundamental in the study of dynamical systems. In holomorphic dynamics, expansion for a function f has frequently been understood in terms of a conformal metric defined …

Dynamics over Q
We describe number theoretic properties of rotations, and some interval maps. All relevant number theory will be explained. Based on arXiv:1806.09446v3.

Morse theory and Thom isomorphism
We use techniques from embedded Morse theory to show an explicit form of Thom isomorphism for oriented vector bundles on manifolds. This is a joint project with Mark Powell.

Center conditions: pull-back of differential equations
The space of polynomial dierential equations of a fixed degree with a center singularity has many irreducible components. We prove that pull-back dierential equations form an irreducible component of such a space. The method used …

Estimating the Hausdorff measure of Denjoy maps by recurrence
We will look at a new method of giving lower bounds on the Hausdorff measure (and dimension) of some fractal sets. The idea is to compute/estimate the consecutive closest return times of a typical point to itself …

Singular stationary measures for random piecewise affine interval homeomorphisms
We consider a family of random dynamical systems consisting of two piecewise affine increasing homeomorphisms $f_-, f_+$ of the unit interval, each with exactly one point of non-differentiability, iterated randomly according to given probability vector. …

Non-autonomous iteration of the exponential family
We shall discuss Julia sets of iterations of functions \lambda_n e^z, where \lambda_n changes at each step. Recall that in the autonomous case the parameter \lambda = 1/e is the largest one for which the …
