A Smooth Curve as a Fractal Under the Third Definition

open access: yes, 2018
It is commonly believed in the literature that smooth curves, such as circles, are not fractal, and only non-smooth curves, such as coastlines, are fractal.

Fractal Continuation

open access: yesConstructive Approximation, 2013
A fractal function is a function whose graph is the attractor of an iterated function system. This paper generalizes analytic continuation of an analytic function to continuation of a fractal function.

On the Lebesgue measure of one generalised set of subsums of geometric series

open access: yesМатематичні Студії
In the present paper, we study a set that can be treated as a generalised set of subsums for a geometric series. This object was discovered independently in various mathematical aspects.

Configurations in fractals [PDF]

open access: yesRocky Mountain Journal of Mathematics, 2021
We define the manifold of configurations to be the quotient set of $k$ points in Euclidean space identified under congruence, and prove that compact subsets of $\mathbb{R}^d, d \geq 2$, of large Hausdorff dimension have a non-null set of configurations in them.
