Common Fixed Points Theorems for Self-Mappings in Menger PM-Spaces

Mathematics, 2022
The purpose of this paper is to prove that orbital continuity for a pair of self-mappings is a necessary and sufficient condition for the existence and uniqueness of a common fixed point for these mappings defined on Menger PM-spaces with a nonlinear ...

Exactly Marginal Operators and Duality in Four Dimensional N=1 Supersymmetric Gauge Theory [PDF]

, 1995
We show that manifolds of fixed points, which are generated by exactly marginal operators, are common in N=1 supersymmetric gauge theory. We present a unified and simple prescription for identifying these operators, using tools similar to those employed ...

The Stationary Behaviour of Fluid Limits of Reversible Processes is Concentrated on Stationary Points [PDF]

, 2012
Assume that a stochastic processes can be approximated, when some scale parameter gets large, by a fluid limit (also called "mean field limit", or "hydrodynamic limit").

On common fixed points, periodic points, and recurrent points of continuous functions

International Journal of Mathematics and Mathematical Sciences, 2003
It is known that two commuting continuous functions on an interval need not have a common fixed point. However, it is not known if such two functions have a common periodic point.

Common Fixed Points for Suzuki-Generalized Nonexpansive Maps

Journal of Applied Mathematics, 2013
A common fixed point theorem for a pair of maps satisfying condition (C) is proved under certain conditions. We extend the well-knownDeMarr's fixed point theorem to the case of noncommuting family of maps satisfying condition (C).

Weak Convergence of Two Iteration Schemes in Banach Spaces [PDF]

Engineering and Technology Journal, 2019
In this paper, we established weak convergence theorems by using appropriate conditions for approximating common fixed points and equivalence between the convergence of the Picard-Mann iteration scheme and Liu et al iteration scheme in Banach spaces.
