Compactifying a convergence space with functions [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
A convergence space is a set together with a convergence structure. In this paper we discuss a method of constructing compactifications on a class of convergence spaces by use of functions.

λ-Statistical Convergence in Paranormed Space [PDF]

open access: yesAbstract and Applied Analysis, 2013
The concept of λ-statistical convergence for sequences of real numbers was introduced in Mursaleen (2000). In this paper, we prove decomposition theorem for λ-statistical convergence.

Weak-Polynomial Convergence on a Banach Space [PDF]

open access: yes, 1993
We show that any super-reflexive Banach space is a LAMBDA-space (i.e., the weak-polynomial convergence for sequences implies the norm convergence). We introduce the notion Of kappa-space (i.e., a Banach space where the weak-polynomial convergence for ...

On Statistical Convergence in Credibility Space [PDF]

open access: yes, 2022
In this paper, we present the notions of statistically convergent sequence for fuzzy variables, statistically Cauchy sequence in credibility space, and present a kind of statistical completeness for credibility space.

Formal Verification of a Topological Spatial Relations Model for Geographic Information Systems in Coq

open access: yesMathematics, 2023
Geographic information systems have undergone rapid growth for decades. Topology has provided valuable modeling tools in the development of this field. Formal verification ofthe model of topological spatial relations can provide a reliable guarantee for ...

Probablistic convergence spaces and regularity

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
The usual definition of regularity for convergence spaces can be characterized by a diagonal axiom R due to Cook and Fischer. The generalization of R to the realm of probabilistic convergence spaces depends on a t-norm T, and the resulting axiom RT ...

The star compactification

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1981
The relationships between a convergence space and its star compactification is studied. Special attention is given to lifting properties of this compactification.

Formalizing Calculus without Limit Theory in Coq

open access: yesMathematics, 2021
Formal verification of mathematical theory has received widespread concern and grown rapidly. The formalization of the fundamental theory will contribute to the development of large projects. In this paper, we present the formalization in Coq of calculus
