Computational reaching of quantified consequences from imperfect initial data
Mathematical Methods in the Applied Sciences, Volume 48, Issue 4, Page 4232-4243, 15 March 2025.Usually, it is not direct to translate theoretical results to practice. One of the challenges is the real computation of solutions to proposed problems, when infinite numbers (such as real numbers or the unit interval) are considered. The same is true when consequences (information) from a data set modeled by logical rules need to be obtained.

Nonlinear Inequality, Fixed Point and NashEquilibrium [PDF]
In this paper, we give new sufficient conditions for the existence of a solution of theg-maximum equality. As a consequence, we prove a new fixed point theorem.

Fixed point theorems for set-valued contraction type maps in metric spaces
, 2010 We first give some fixed point results for set-valued self-map contractions in complete metric spaces. Then we derive a fixed point theorem for nonself set-valued contractions which are metrically inward. Our results generalize many well-known results in

, 2010 We propose a method to characterize the fixed points described in Tarski's theorem for complete lattices. The method is deductive: the least and greatest fixed points are "proved" in some inference system defined from deduction rules.

On A Fixed Point Theorem For The Product Of Operators
, 2017 In this paper, we study the existence of fixed points for the product of nonlinear operators. This kind of fixed point theorems is necessary in consideration of quadratic differential and integral problems.

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 ...

Two versions of Tarski fixed point theorem applied to fuzzy set equations and inequations
, 2021 The set of all fuzzy subsets of a given set and the set of all fuzzy relations on a given set are complete lattices, provided that the codomain lattice is complete. That gives us an opportunity to apply Tarski fixed point theorem to some typical fuzzy set and fuzzy relational equations, the solutions to which are the fixed points of a monotonous ...
