ON THE SMARANDACHE FUNCTION AND THE FIXED - POINT THEORY OF NUMBERS [PDF]
, 1986 This brief note points out several basic connections between the Smarandache function, fixed-point theory and prime-number theory. First recall that fixed-point theory in function spaces provides elegent, if not short, proofs of the existence of ...

$FG$-coupled fixed point theorems in cone metric spaces
Karpatsʹkì Matematičnì Publìkacìï, 2018 The concept of $FG$- coupled fixed point introduced recently is a generalization of coupled fixed point introduced by Guo and Lakshmikantham. A point $(x,y)\in X\times X$ is said to be a coupled fixed point of the mapping $F: X\times X \rightarrow X$ if $

Demonstratio Mathematica, 1996 Let \((X,d)\) be a bounded metric space and \(T:X\to \text{CB} (X)\) a set-valued mapping. Let \(O(x)\) be the orbit of \(x\) by the mapping \(T\) and let \(\delta(A,B)\) be the diameter of the pair \(A,B\subset X\). The author gives some strict fixed point theorems for some set-valued mappings which satisfy the following condition \[ \delta (Tx,Ty ...

A NOTE ON BRØNDSTED’S FIXED POINT THEOREM
Bulletin of the Australian Mathematical Society, 2023 AbstractWe show that for the case of uniformly convex Banach spaces, the conditions of Brøndsted’s fixed point theorem can be relaxed.

Measures of weak noncompactness and fixed point theory in banach algebras satisfying condition (P)
, 2017 The aim of this paper is to prove some new fixed point theorems in a nonempty closed convex subset of a Banach algebra satisfying a sequential condition (P) in a weak topology setting.peer ...

Advanced Energy Materials, EarlyView.In this work, we developed a phase‐stability predictor by combining machine learning and ab initio thermodynamics approaches, and identified the key factors determining the favorable phase for a given composition. Specifically, a lower TM ionic potential, higher Na content, and higher mixing entropy favor the O3 phase.

General equilibrium and fixed point theory : a partial survey [PDF]
Focusing mainly on equilibrium existence results, this paper emphasizes the role of fixed point theorems in the development of general equilibrium theory, as well for its standard definition as for some of its extensions.Fixed point, equilibrium ...

Temperature Sensitivity and Adaptation of Cereal Yields: Empirical Evidence From Italy
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT This paper investigates the evolving temperature sensitivity and climate adaptation of cereal yields in Italy from 1952 to 2023, using province‐level data for maize, common wheat, and durum wheat. Employing panel data econometric methods, we estimate yield responses to heat exposure, changes in sensitivity over time, and adaptation to climate ...
