In 1980, Albert Fathi asked whether the group of area-preserving homeomorphisms of the 2-disc that are the identity near the boundary is a simple group. In this paper, we show that the simplicity of… (More)

In [23], Mary Rees has constructed a minimal homeomorphism of the 2-torus with positive topological entropy. This homeomorphism f is obtained by enriching the dynamics of an irrational rotation R. We… (More)

Consider a homeomorphism h of the closed annulus S · [0, 1], isotopic to the identity, such that the rotation set of h is reduced to a single irrational number ˺ (we say that h is an irrational… (More)

The Kalkkop structure, a circular depression with a diameter of 640 m, is situated in the Eastern Cape Province, South Africa. In 1992, a bore hole was drilled in the center of the crater to a depth… (More)

In this paper, we study pseudo-rotations of the open annulus, i.e. conservative homeomorphisms of the open annulus whose rotation set is reduced to a single irrational number (the angle of the… (More)

The analysis of speech onset times has a longstanding tradition in experimental psychology as a measure of how a stimulus influences a spoken response. Yet the lack of accurate automatic methods to… (More)

In [GP], Gambaudo and Pécou introduced the “linking property” to study the dynamics of germs of planar homeomorphims and provide a new proof of Naishul theorem. In this paper we prove that the… (More)

We prove that the family of measured dynamical systems which can be realised as uniquely ergodic minimal homeomorphisms on a given manifold (of dimension at least two) is stable under measured… (More)

We construct different types of quasiperiodically forced circle homeomorphisms with transitive but non-minimal dynamics. Concerning the recent Poincaré-like classification for this class of maps of… (More)

We discuss boundedness and distortion in transformation groups. We show that the groups Diff0(R) and Diff (Rn) have the strong distortion property, whenever 0 ≤ r ≤ ∞, r 6= n+ 1. This implies in… (More)
