Möbius iterated function systems [PDF]

open access: yesTransactions of the American Mathematical Society, 2012
Iterated function systems have been most extensively studied when the functions are affine transformations of Euclidean space and, more recently, projective transformations on real projective space. This paper investigates iterated function systems consisting of Möbius transformations on the extended complex plane or, equivalently, on the Riemann ...

Some New Difference Inequalities and an Application to Discrete-Time Control Systems

open access: yesJournal of Applied Mathematics, 2012
Two new nonlinear difference inequalities are considered, where the inequalities consist of multiple iterated sums, and composite function of nonlinear function and unknown function may be involved in each layer.

Analyzing Convergence in Sequences of Uncountable Iterated Function Systems—Fractals and Associated Fractal Measures

open access: yesMathematics
In this paper, we examine a sequence of uncountable iterated function systems (U.I.F.S.), where each term in the sequence is constructed from an uncountable collection of contraction mappings along with a linear and continuous operator.

Multi Fractals of Generalized Multivalued Iterated Function Systems in b-Metric Spaces with Applications

open access: yesMathematics, 2019
In this paper, we obtain multifractals (attractors) in the framework of Hausdorff b-metric spaces. Fractals and multifractals are defined to be the fixed points of associated fractal operators, which are known as attractors in the literature of fractals.

New fixed point results in quasi-metric spaces and applications in fractals theory

open access: yesAdvances in Difference Equations, 2019
In this paper, we prove some fixed point theorems for ψF-contractions in the framework of quasi-metric spaces generalizing and improving several similar results in metric spaces.

From set-valued dynamical processes to fractals [PDF]

open access: yesOpuscula Mathematica
We present a general theory of topological semiattractors and attractors for set-valued semigroups. Our results extend and unify those previously obtained by Lasota and Myjak.

Cantor Type Attractors in Stochastic Growth Models. [PDF]

open access: yes
We study a one-sector stochastic optimal growth model where production is affected by a shock taking one of two values. Such exogenous shock may enter multiplicatively or additively.

Hypercomplex Iterated Function Systems

open access: yes, 2021
We introduce the novel concept of hypercomplex iterated function system (IFS) on the complete metric space $(\mathbb{A}_{n+1}^k,d)$ and define its hypercomplex attractor. Systems of hypercomplex function systems arising from hypercomplex IFSs and their backward trajectories are also introduced and it is shown that the attractors of such backward ...

The contraction mapping principle and some applications

open access: yesElectronic Journal of Differential Equations, 2009
These notes contain various versions of the contraction mapping principle. Several applications to existence theorems in the theories of differential and integral equations and variational inequalities are given.
