On quantum iterated function systems

open access: yesOpen Physics, 2004
Quantum Iterated Function System on a complex projective space is defined by a family of linear operators on a complex Hilbert space. The operators define both the maps and their probabilities by one algebraic formula.

The Proof of a Conjecture Relating Catalan Numbers to an Averaged Mandelbrot-Möbius Iterated Function

open access: yesFractal and Fractional, 2021
In 2021, Mork and Ulness studied the Mandelbrot and Julia sets for a generalization of the well-explored function ηλ(z)=z2+λ. Their generalization was based on the composition of ηλ with the Möbius transformation μ(z)=1z at each iteration step ...

Accelerated Iterated Filtering

open access: yesAustrian Journal of Statistics, 2023
Simulation-based inferences have attracted much attention in recent years, as the direct computation of the likelihood function in many real-world problems is difficult or even impossible.

Cyclic weak ϕ iterated function system

open access: yesTopological Algebra and its Applications, 2022
In this article, we are considering the cyclic weak ϕ-contraction and prove that the result is also true in Hausdorff metric space. We are constructing a cyclic weak ϕ iterated function system (IFS), which gives the self-referential set or attractor ...

Fractal Interpolation Using Harmonic Functions on the Koch Curve

open access: yesFractal and Fractional, 2021
The Koch curve was first described by the Swedish mathematician Helge von Koch in 1904 as an example of a continuous but nowhere differentiable curve.

On the Fractal interpolation functions associated with Matkowski contractions

open access: yesElectronic Research Archive, 2023
In this paper we investigate an iterated function system that defines a fractal interpolation function, where ordinate scaling, that is Lipschitz constant in Banach contraction principle is substituted by real-valued control function.

Generalized Iterated Function Systems on b-Metric Spaces

open access: yesMathematics, 2023
An iterated function system consists of a complete metric space (X,d) and a finite family of contractions f1,⋯,fn:X→X. A generalized iterated function system comprises a finite family of contractions defined on the Cartesian product Xm with values in X ...

Law of the Iterated Logarithm for some Markov operators [PDF]

open access: yes, 2015
The Law of the Iterated Logarithm for some Markov operators, which converge exponentially to the invariant measure, is established. The operators correspond to iterated function systems which, for example, may be used to generalize the cell cycle model ...

Fractals via Controlled Fisher Iterated Function System

open access: yesFractal and Fractional, 2022
This paper explores the generalization of the fixed-point theorem for Fisher contraction on controlled metric space. The controlled metric space and Fisher contractions are playing a very crucial role in this research.
