In this short note, we show that the inradius of a convex body is comparable to its volume divided by its surface area. We also give a simple formula, in terms of its volume and inradius, that is comparable to the volume of its intersection with the $\varepsilon$-neighbourhood of its boundary, and provide an application of this to self-projective attractors with convex holes.
In this article we extend results of Kakutani, Adler-Flatto, Smilansky and others on the classical $α$-Kakutani equidistribution result for sequences arising from finite partitions of the interval. In particular, we describe a generalization of the equidistribution result to infinite partitions. In addition, we give discrepancy estimates, extending results of Drmota-Infusino.
We prove a packing exponent formula for the upper box-counting dimension of attractors of certain projective iterated function systems. This partially affirms a conjecture of De Leo, and gives that the box-counting dimension of the Rauzy gasket $\mathcal R$, $\operatorname{dim}_B(\mathcal R)$, exists and satisfies $\operatorname{dim}_B(\mathcal R) = \operatorname{dim}_H(\mathcal R) \in [1.6196,1.7415].$
In this note, we give an elementary proof that the Hausdorff dimension of the Rauzy gasket is at most 1.7407, improving upon results of Avila et al. and Fougeron.
We present a purely elementary proof that the Rauzy gasket has Hausdorff dimension strictly smaller than two.
In [23], Slipantschuk, Bandtlow and Just gave concrete examples of Anosov diffeomorphisms of the two-torus for which their resonances could be completely described. Their approach was based on composition operators acting on analytic anisotropic Hilbert spaces, and in this note we present a construction of alternative anisotropic Hilbert spaces which helps to simplify parts of their analysis and gives scope for constructing further examples.
