Demonstratio Mathematica, 2019 In this paper, we provide some generalizations of the Darbo’s fixed point theorem associated with the measure of noncompactness and present some results on the existence of the coupled fixed point theorems for a special class of operators in a Banach ...

Journal of Function Spaces, Volume 2026, Issue 1, 2026.The present paper develops a new two‐step iterative method, referred to as the P∗ iteration, for the approximation of fixed points of weak contractions mappings in Banach spaces. The theoretical analysis establishes the strong convergence of the proposed scheme to the unique fixed point, along with its almost I‐stability.

Generalized split null point of sum of monotone operators in Hilbert spaces
Demonstratio Mathematica, 2021 In this paper, we introduce a new type of a generalized split monotone variational inclusion (GSMVI) problem in the framework of real Hilbert spaces. By incorporating an inertial extrapolation method and an Halpern iterative technique, we establish a ...

Polynomial Fuzzy Contractions With Applications to SEIRV Epidemic Models
Journal of Function Spaces, Volume 2026, Issue 1, 2026.In this study, a new family of polynomial‐type fuzzy contractions defined on metric spaces is introduced. Under filtered assumptions, it is demonstrated that such non‐crisp set‐valued operators possess some fixed points. Because of the higher‐order terms polynomial nature of the contractions, a few important corollaries, some of which drop to existing ...

Convergence of Picard–CR Iterative Algorithm and Applications
Journal of Function Spaces, Volume 2026, Issue 1, 2026.In applied mathematics, graph theory (GT) is a notably compelling area of study. In the last 50 years, the number of mathematicians making contributions to research in this field has consistently increased. This rising interest is mainly a result of the significant real‐world applications it offers.

Journal of Function Spaces, Volume 2026, Issue 1, 2026.The aim of this paper is to present a novel stationary and nonstationary iterative approach for approximating common fixed points of a finite family of generalized nonexpansive mappings in uniformly convex Banach spaces. For the stationary scheme, both strong and weak convergence theorems are established under standard geometric conditions.

Persistence landscapes of affine fractals
Demonstratio Mathematica, 2022 We develop a method for calculating the persistence landscapes of affine fractals using the parameters of the corresponding transformations. Given an iterated function system of affine transformations that satisfies a certain compatibility condition, we ...

Journal of Function Spaces, Volume 2026, Issue 1, 2026.We study the relation between the weakest contractivity criteria along Picard trajectories and the class of almost weakly Picard operators (AWPOs) in b‐metric spaces. For a self‐map T on a b‐metric space, we consider two uniform regularity conditions on Picard orbits: (W1), which controls arbitrary pairs of iterates, and its weaker counterpart (W2 ...
