Digital fixed points, approximate fixed points, and universal functions
Applied General Topology, 2016 A. Rosenfeld [23] introduced the notion of a digitally continuous function between digital images, and showed that although digital images need not have fixed point properties analogous to those of the Euclidean spaces modeled by the images, there often are approximate fixed point properties of such images.

A fixed point theorem for COFEs [PDF]
arXiv, 2023 A new fixed point principle for complete ordered families of equivalences (COFEs) is presented, which is stronger than the standard Banach-type fixed point principle.

Nontrivial fixed point in nonabelian models [PDF]
, 2000 We investigate the percolation properties of equatorial strips in the two-dimensional O(3) nonlinear $\sigma$ model. We find convincing evidence that such strips do not percolate at low temperatures, provided they are sufficiently narrow.

A Regular Gonosomal Evolution Operator with uncountable set of fixed points [PDF]
arXiv, 2021 In this paper we study dynamical systems generated by a gonosomal evolution operator of a bisexual population. We find explicitly all (uncountable set) of fixed points of the operator. It is shown that each fixed point has eigenvalues less or equal to 1. Moreover, we show that each trajectory converges to a fixed point, i.e.

Fixed point theory in terms of a metric and of an order relation
Fixed Point Theory, 2019 We consider a nonempty set X endowed with a metric d an order relation and an operator f : X → X, which satisfies two main assumptions: (1) f is generalized monotone with respect to ; (2) f is a (generalized) contraction with respect to d on a certain ...

A note on the relationship between the isotone assumption of the Abian-Brown fixed point theorem and Abian’s most basic fixed point theorem [PDF]
, 2014 In a recent paper Xie et al. (Fixed Point Theory Appl. 2013:192, 2013) gave several extensions and some applications of the Abian-Brown (AB) fixed point theorem.

A Generalization of b-Metric Space and Some Fixed Point Theorems
, 2017 In this paper, inspired by the concept of b-metric space, we introduce the concept of extended b-metric space. We also establish some fixed point theorems for self-mappings defined on such spaces.

A new contribution to discontinuity at fixed point [PDF]
Fixed Point Theory, 2017 The aim of this paper is to obtain new solutions to the open question on the existence of a contractive condition which is strong enough to generate a fixed point but which does not force the map to be continuous at the fixed point.

Analysis and Geometry in Metric Spaces, 2023 This article analyses two schemes: Mann-type and viscosity-type proximal point algorithms. Using these schemes, we establish Δ-convergence and strong convergence theorems for finding a common solution of monotone vector field inclusion problems, a ...
