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 couple of examples, and we define concepts related to these in order to motivate several questions and open problems. In particular we generalize the notion of Veech group to dilation surfaces, and we prove a structure result about these Veech groups. 

Veech Groups and Triangulations of Half-Dilation Pillowcases

In this paper we consider the symmetries of triangulable half-dilation structures on the sphere with four singularities. We show that all such surfaces can be produced by a tetrahedral construction.

Closed geodesics in dilation surfaces

We introduce the notion of exotic dilation surface, which provides a way to produce a weak form of compactification of the moduli space of dilation surfaces. This notion is devised to enable one to

The Realization Problem for Dilation Surfaces

Dilation surfaces, or twisted quadratic differentials, are variants of translation surfaces. In this paper, we study the question of what elements or subgroups of the mapping class group can be

Moduli spaces of complex affine and dilation surfaces

. We construct moduli spaces of complex affine and dilation surfaces. Using ideas of Veech [Vee93] , we show that the the moduli space A g,n ( m ) of genus g affine surfaces with cone points of complex

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

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 trajectories on a

Internal-wave billiards in trapezoids and similar tables

We call internal-wave billiard the dynamical system of a point particle that moves freely inside a planar domain (the table) and is reflected by its boundary according to this rule: reflections are

On Limit Sets for Geodesics of Meromorphic Connections

Meromorphic connections on Riemann surfaces originate and are closely related to the classical theory of linear ordinary differential equations with meromorphic coefficients. Limiting behaviour of



Branched structures on Riemann surfaces

Following results of Gunning on geometric realizations of projective structures on Riemann surfaces, we investigate more fully certain generalizations of such structures. We define the notion of a

On the relations between branched structures and affine and projective bundles on Riemann surfaces

A classification for analytic branched G-structures on a Riemann surface M is provided by means of a map (G into the moduli spaces of flat G-bundles on M. (G = GA(1, C) or PL(1, C).) Conditions are

Flat Surfaces

Various problems of geometry, topology and dynamical systems on surfaces as well as some questions concerning one-dimensional dynamical systems lead to the study of closed surfaces endowed with a

Affine interval exchange maps with a wandering interval

For almost all interval exchange maps (i.e.m.) T0, with combinatorics of genus g ⩾ 2, we construct affine i.e.m. T that are semi‐conjugate to T0 and have a wandering interval.

Persistence of wandering intervals in self-similar affine interval exchange transformations

It is proved that given a self-similar interval exchange transformation T(λ,π), whose associated matrix verifies a quite general algebraic condition, there exists an affine interval exchange transformed with wandering intervals that is semi-conjugated to it.

Affine interval exchange transformations with wandering intervals

There exist uniquely ergodic bijective affine interval exchange transformations of $[0,1)$ having wandering intervals and such that the support of the invariant measure is a Cantor set.
