On the Hausdorff dimension of the Rauzy gasket
Artur Avila, Pascal Hubert, Alexandra Skripchenko
In this paper, we prove that the Hausdorff dimension of the Rauzy gasket is less than 2. By this result, we answer a question addressed by Pierre Arnoux. Also, this question is a v…
Asymptotically periodic piecewise contractions of the interval
Arnaldo Nogueira, Benito Pires, Rafael A. Rosales
We consider the iterates of a generic injective piecewise contraction of the interval defined by a finite family of contractions. Let , , be -…
When periodicities enforce aperiodicity
Nicolas Bédaride, Thomas Fernique
Aperiodic tilings are non-periodic tilings defined by local rules. They are widely used to model quasicrystals, and a central question is to understand which of the non-periodic ti…
Poisson Lie Sigma Models
Boris Arm
A Manin triples (D; g; ~ g) is a bialgebra (g; ~ g which don't intersect each others and a direct sum of this bialgebra D = g ~ g). If the corresponding Lie groups have a Poisson s…
Asymptotic self-similarity and order-two ergodic theorems for renewal flows
Albert M. Fisher, Marina Talet
We prove a log average almost-sure invariance principle (log asip) for renewal processes with positive i.i.d. gaps in the domain of attraction of an -stable law with . Dy…
Random product of substitutions with the same incidence matrix
Pierre Arnoux, Masahiro Mizutani, Tarek Sellami
Any infinite sequence of substitutions with the same matrix of the Pisot type defines a symbolic dynamical system which is minimal. We prove that, to any such sequence, we can asso…
