Dimension of the intersection of certain Cantor sets in the plane [PDF]

open access: yesOpuscula Mathematica, 2021
In this paper we consider a retained digits Cantor set \(T\) based on digit expansions with Gaussian integer base. Let \(F\) be the set all \(x\) such that the intersection of \(T\) with its translate by \(x\) is non-empty and let \(F_{\beta}\) be the ...

Computability of Self‐Similar Sets [PDF]

open access: yesMathematical Logic Quarterly, 1999
AbstractWe investigate computability of a self‐similar set on a Euclidean space. A nonempty compact subset of a Euclidean space is called a self‐similar set if it equals to the union of the images of itself by some set of contractions. The main result in this paper is that if all of the contractions are computable, then the self‐similar set is a ...

Optimized Self-Similar Borel Summation

open access: yesAxioms, 2023
The method of Fractional Borel Summation is suggested in conjunction with self-similar factor approximants. The method used for extrapolating asymptotic expansions at small variables to large variables, including the variables tending to infinity, is ...

On the structure of self-affine Jordan arcs in ℝ2

open access: yesDemonstratio Mathematica, 2023
We prove that if a self-affine arc γ∈R2\gamma \in {{\mathbb{R}}}^{2} does not satisfy weak separation condition, then it is a segment of a parabola or a straight line.

Elementary Fractal Geometry. 2. Carpets Involving Irrational Rotations

open access: yesFractal and Fractional, 2022
Self-similar sets with the open set condition, the linear objects of fractal geometry, have been considered mainly for crystallographic data. Here we introduce new symmetry classes in the plane, based on rotation by irrational angles.

Multiple codings of self-similar sets with overlaps [PDF]

open access: yesAdvances in Applied Mathematics, 2021
In this paper we consider a general class $\mathcal E$ of self-similar sets with complete overlaps. Given a self-similar iterated function system $Φ=(E, \{f_i\}_{i=1}^m)\in\mathcal E$ on the real line, for each point $x\in E$ we can find a sequence $(i_k)=i_1i_2\ldots\in\{1,\ldots,m\}^\mathbb N$, called a coding of $x$, such that $$ x=\lim_{n\to\infty ...

Hölder Parameterization of Iterated Function Systems and a Self-Affine Phenomenon

open access: yesAnalysis and Geometry in Metric Spaces, 2021
We investigate the Hölder geometry of curves generated by iterated function systems (IFS) in a complete metric space. A theorem of Hata from 1985 asserts that every connected attractor of an IFS is locally connected and path-connected.

Quasiperiodic Patterns of the Complex Dimensions of Nonlattice Self-Similar Strings, via the LLL Algorithm

open access: yesMathematics, 2021
The Lattice String Approximation algorithm (or LSA algorithm) of M. L. Lapidus and M. van Frankenhuijsen is a procedure that approximates the complex dimensions of a nonlattice self-similar fractal string by the complex dimensions of a lattice self ...

A p.c.f. self-similar set with no self-similar energy [PDF]

open access: yesJournal of Fractal Geometry, Mathematics of Fractals and Related Topics, 2019
An example of a p.c.f. ( post-critically finite ) self-similar set without eigenform for any set of weights, is provided. The existence of an eigenform on such sets was an important, long-standing open problem in analysis on fractals.
