On the dimension of Bernoulli convolutions

The Bernoulli convolution with parameter $\lambda\in(0,1)$ is the probability measure $\mu_\lambda$ that is the law of the random variable $\sum_{n\ge0}\pm\lambda^n$, where the signs are independent

The Bernoulli convolution $\nu_\lambda$ with parameter $\lambda\in(0,1)$ is the probability measure supported on $\mathbf{R}$ that is the law of the random variable $\sum\pm\lambda^n$, where the

On the Hausdorff Dimension of Bernoulli Convolutions

An expression for the Garsia entropy of Bernoulli convolutions in terms of products of matrices is given that shows that one can calculate the Hausdorff dimension of the Bernouelli convolution to arbitrary given accuracy whenever $\beta $ is algebraic.

On the dimension of Furstenberg measure for random matrix products

Letμ be ameasure on SL2(R) generating a non-compact and totally irreducible subgroup, and let ν be the associated stationary (Furstenberg) measure for the action on the projective line. We prove that

Hausdorff dimension of planar self-affine sets and measures

A Dichotomy for the dimension of solenoidal attractors on high dimensional space

We study dynamical systems generated by skew products: T : [0, 1) × C→ [0, 1) × C T (x, y) = (bx mod 1, γy + φ(x)) where integer b ≥ 2, γ ∈ C such that 0 < |γ| < 1, and φ is a real analytic

Here and in the following we shall suppose that this condition is satisfied. It is easy to show that F(x, r) is continuous. Since it can be shown (see [4]) that it is always "pure," i.e. either

The results include differential-entropy versions of Ruzsa's triangle inequality, the Plünnecke-Ruzsa inequality, and the Balog-Szemerédi-Gowers lemma, and a differential entropy version of a Freiman-type inverse-sumset theorem, which can be seen as a quantitative converse to the entropy power inequality.
