Almost uniform domains and Poincaré inequalities

open access: yesTransactions of the London Mathematical Society, 2021
Here we show existence of many subsets of Euclidean spaces that, despite having empty interior, still support Poincaré inequalities with respect to the restricted Lebesgue measure.

Persistence landscapes of affine fractals

open access: yesDemonstratio Mathematica, 2022
We develop a method for calculating the persistence landscapes of affine fractals using the parameters of the corresponding transformations. Given an iterated function system of affine transformations that satisfies a certain compatibility condition, we ...

How long is the chaos game?

open access: yesBulletin of the London Mathematical Society, Volume 53, Issue 6, Page 1749-1765, December 2021., 2021
Abstract In the 1988 textbook Fractals Everywhere, Barnsley introduced an algorithm for generating fractals through a random procedure which he called the chaos game. Using ideas from the classical theory of covering times of Markov chains, we prove an asymptotic formula for the expected time taken by this procedure to generate a δ‐dense subset of a ...

Graph‐like spaces approximated by discrete graphs and applications

open access: yesMathematische Nachrichten, Volume 294, Issue 11, Page 2237-2278, November 2021., 2021
Abstract We define a distance between energy forms on a graph‐like metric measure space and on a suitable discrete weighted graph using the concept of quasi‐unitary equivalence. We apply this result to metric graphs, graph‐like manifolds (e.g. a small neighbourhood of an embedded metric graph) or pcf self‐similar fractals as metric measure spaces with ...

Dimension of ergodic measures projected onto self‐similar sets with overlaps

open access: yesProceedings of the London Mathematical Society, Volume 122, Issue 2, Page 191-206, February 2021., 2021
Abstract For self‐similar sets on R satisfying the exponential separation condition we show that the dimension of natural projections of shift invariant ergodic measures is equal to min{1,h−χ}, where h and χ are the entropy and Lyapunov exponent, respectively. The proof relies on Shmerkin's recent result on the Lq dimension of self‐similar measures. We

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.

The structure of fuzzy fractals generated by an orbital fuzzy iterated function system

open access: yesDemonstratio Mathematica, 2023
In this article, we present a structure result concerning fuzzy fractals generated by an orbital fuzzy iterated function system ((X,d),(fi)i∈I,(ρi)i∈I)\left(\left(X,d),{({f}_{i})}_{i\in I},{\left({\rho }_{i})}_{i\in I}). Our result involves the following

Sampling and interpolation of cumulative distribution functions of Cantor sets in [0, 1]

open access: yesDemonstratio Mathematica, 2021
Cantor sets are constructed from iteratively removing sections of intervals. This process yields a cumulative distribution function (CDF), constructed from the invariant Borel probability measure associated with their iterated function systems.
