On Infinitely generated Fuchsian groups of the Loch Ness monster, the Cantor tree and the Blooming Cantor tree

open access: yesComplex Manifolds, 2019
In this paper, for a non-compact Riemman surface S homeomorphic to either: the Infinite Loch Ness monster, the Cantor tree and the Blooming Cantor tree, we give a precise description of an infinite set of generators of a Fuchsian group Γ < PSL(2, ℝ ...

Badly approximable vectors on a vertical Cantor set [PDF]

open access: yes, 2012
For $i, j > 0, i + j = 1$, the set of badly approximable vectors with weight $(i, j)$ is defined by $Bad(i, j) = \{(x, y) \in \R^2 : \exists c > 0 \forall q\in\N, \;\; \max\{q||qx||^{1/i}, q||qy||^{1/j} \} > c\}$, where $||x||$ is the distance of $x$ to ...

Cantor Limit Set of a Topological Transformation Group on S1

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
The limit set of a topological transformation group on S1 generated by two generators is proved to be totally disconnected (or thin) and perfect if the conditions (i–v) are satisfied. A concrete application to a Doubly Periodic Riccati equation is given.

Unambiguous Tree Languages Are Topologically Harder Than Deterministic Ones [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
The paper gives an example of a tree language G that is recognised by an unambiguous parity automaton and is analytic-complete as a set in Cantor space.

Vanishing sums of roots of unity and the Favard length of self-similar product sets

open access: yesDiscrete Analysis, 2022
Vanishing sums of roots of unity and the Favard length of self-similar product sets, Discrete Analysis 2022:19, 31 pp. An important theme in geometric measure theory is the typical size of a set when it is randomly projected. For example, suppose that $

A Conversation on Divine Infinity and Cantorian Set Theory [PDF]

open access: yes, 2012
This essay is written as a drama that opens with Aristotle, St. Augustine of Hippo, St. Thomas Aquinas, and Nicholas of Cusa debating the nature and reality of infinity, introducing historical concepts such as potential, actual, and divine infinity ...

Resonance between Cantor sets [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2009
AbstractLet Ca be the central Cantor set obtained by removing a central interval of length 1−2a from the unit interval, and then continuing this process inductively on each of the remaining two intervals. We prove that if log b/log a is irrational, then where dim is Hausdorff dimension.

Primality, Fractality, and Image Analysis

open access: yesEntropy, 2019
This paper deals with the hidden structure of prime numbers. Previous numerical studies have already indicated a fractal-like behavior of prime-indexed primes. The construction of binary images enables us to generalize this result.

Remainders, Singular Sets and the Cantor Set

open access: yesRocky Mountain Journal of Mathematics, 1994
The authors characterize when, for nonlocally compact \(X\), there is a compactification \(\alpha X\) of \(X\) for which the closure of \(\alpha X\smallsetminus X\) is homeomorphic to the Cantor set \(2^ \omega\).
