A priori bounds for GIETs, affine shadows and rigidity of foliations in genus two

S Ghazouani, C Ulcigrai - Publications mathématiques de l'IHÉS, 2023 - Springer
We prove a rigidity result for foliations on surfaces of genus two, which can be seen as a
generalization to higher genus of Herman's theorem on circle diffeomorphisms and …

Dynamics and'arithmetics' of higher genus surface flows

C Ulcigrai - arXiv preprint arXiv:2207.06404, 2022 - arxiv.org
We survey some recent advances in the study of (area-preserving) flows on surfaces, in
particular on the typical dynamical, ergodic and spectral properties of smooth area …

[HTML][HTML] Rigidity for piecewise smooth homeomorphisms on the circle

K Cunha, D Smania - Advances in Mathematics, 2014 - Elsevier
We find conditions for two piecewise C 2+ ν homeomorphisms f and g of the circle to be C 1
conjugate. Besides the restrictions on the combinatorics of the maps (we assume that the …

Time-changes of Heisenberg nilflows

G Forni, A Kanigowski - arXiv preprint arXiv:1711.05543, 2017 - arxiv.org
We consider the three dimensional Heisenberg nilflows. Under a full measure set
Diophantine condition on the generator of the flow we construct Bufetov functionals which …

Cascades in the dynamics of affine interval exchange transformations

A Boulanger, C Fougeron… - Ergodic theory and …, 2020 - cambridge.org
We describe in this article the dynamics of a one-parameter family of affine interval
exchange transformations. This amounts to studying the directional foliations of a particular …

Dilation surfaces and their Veech groups

E Duryev, C Fougeron… - Journal of modern …, 2019 - hal.sorbonne-universite.fr
We introduce a class of objects which we call'dilation surfaces'. These provide families of
foliations on surfaces whose dynamics we are interested in. We present and analyze a …

Triangle tiling billiards and the exceptional family of their escaping trajectories: circumcenters and Rauzy gasket

P Hubert, O Paris-Romaskevich - Experimental Mathematics, 2022 - Taylor & Francis
Consider a periodic tiling of a plane by equal triangles obtained from the equilateral tiling by
a linear transformation. We study a following tiling billiard: a ball follows straight segments …

Angels' staircases, Sturmian sequences, and trajectories on homothety surfaces

J Bowman, S Sanderson - arXiv preprint arXiv:1806.04129, 2018 - arxiv.org
A homothety surface can be assembled from polygons by identifying their edges in pairs via
homotheties, which are compositions of translation and scaling. We consider linear …
