Strong convergence theorems and rate of convergence of multi-step iterative methods for continuous mappings on an arbitrary interval [PDF]
Fixed Point Theory and Applications, 2012 In this article, by using the concept of W-mapping introduced by Atsushiba and Takahashi and K-mapping introduced by Kangtunyakarn and Suantai, we define W(T,N)-iteration and K(T,N)-iteration for finding a fixed point of continuous mappings on an ...

Annales Mathematicae Silesianae, 2020 The paper consists of two parts. At first, assuming that (Ω, A, P) is a probability space and (X, ϱ) is a complete and separable metric space with the σ-algebra of all its Borel subsets we consider the set c of all ⊗ 𝒜-measurable and contractive in ...

On a functional equation involving iterates and powers
Advances in Differential Equations, 2014 We present a complete list of all continuous solutions f:(0,+∞)→(0,+∞) of the equation f2(x)=γ[f(x)]αxβ, where α, β and γ>0 are given real numbers.MSC:39B22, 39B12, 26A18.

Controlled K-Fusion Frame for Hilbert Spaces
Moroccan Journal of Pure and Applied Analysis, 2021 K-fusion frames are a generalization of fusion frames in frame theory. In this paper, we extend the concept of controlled fusion frames to controlled K-fusion frames, and we develop some results on the controlled K-fusion frames for Hilbert spaces, which

On the convergence of an iteration method for continuous mappings on an arbitrary interval
Fixed Point Theory and Applications, 2013 In this paper, we consider an iterative method for finding a fixed point of continuous mappings on an arbitrary interval. Then, we give the necessary and sufficient conditions for the convergence of the proposed iterative methods for continuous mappings ...

Advances in Nonlinear Analysis, 2020 It is well known that C2-transformation φ of the unit interval into itself with a Markov partition (2.1) π = {Ik : k ∈ K} admits φ-invariant density g (g ≥ 0, ∥g∥ = 1) if: (2.2) ∣(φn)′∣ ≥ C1 > 1 for some n (expanding condition); (2.3) ∣φ″(x)/(φ′(y))2 ...

Studies on concave Young-functions [PDF]
, 2005 We succeeded to isolate a special class of concave Young-functions enjoying the so-called \emph{density-level property}. In this class there is a proper subset whose members have each the so-called degree of contraction denoted by $c^{\ast}$, and map ...
