چکیده

Let ( , σ ) be the one-sided shift space onm symbols. For any x = (xi)i 1 ∈ and positive integer n, define Rn(x) = inf{j n : x1x2 · · · xn = xj+1xj+2 · · · xj+n}. We prove that for each pair of numbersα, β ∈ [0,∞] withα β, the following recurrent set Eα,β = { x ∈ : lim inf n→∞ logRn(x) n = α, lim sup n→∞ logRn(x) n = β } has Hausdorff dimension one.

Dimension and Dynamics for Fractal Recurrent Sets

The fractal 'recurrent sets' defined by F. M. Dekking are analysed using subshifts of finite type. We show how Dekking's method is related to a construction due to J. Hutchinson, and prove a conjecture of Dekking concerning conditions under which the best general upper bound for the Hausdorff dimension for recurrent sets is actually equal to the Hausdorff dimension. Introduction Since the publi...

Dimension of Besicovitch-eggleston Sets in Countable Symbolic Space

This paper is mainly concerned with Hausdorff dimensions of Besicovitch-Eggleston subsets in countable symbolic space. A notable point is that, the dimension values posses a universal lower bound depending only on the underlying metric. As a consequence of the main results, we obtain Hausdorff dimension formulas for sets of real numbers with prescribed digit frequencies in their Lüroth expansions.

Function spaces and Hausdorff dimension on fractals

We start by surveying a possible approach for function spaces of Besov type on special closed subsets of Rn. Afterwards we recall that, in the case of Sobolev spaces and Besov spaces on Rn, the Hausdorff dimension for the graphs of continuous functions belonging to such spaces has been studied by several authors, and that in the case of Besov spaces the final answer concerning the maximal possi...

Dimensions of Some Fractals Defined via the Semigroup

We compute the Hausdorff and Minkowski dimension of subsets of the symbolic space Σm = {0, ..., m−1}N that are invariant under multiplication by integers. The results apply to the sets {x ∈ Σm : ∀ k, xkx2k · · ·xnk = 0}, where n ≥ 3. We prove that for such sets, the Hausdorff and Minkowski dimensions typically differ.
