L-fuzzy N-convergence structures
Journal of Intelligent & Fuzzy Systems, 2016Based on a completely distributive lattice L, the concept of L-fuzzy N-convergence structures is introduced. It is shown that the category of L-fuzzy topological spaces can be embedded in the category of L-fuzzy N-convergence spaces. It is also proved the category of (topological) pretopological L-fuzzy N-convergence spaces is isomorphic to the ...

Fuzzy Convergence, Fuzzy Neighborhood Convergence and I-Tolerance Structures for Groups
New Mathematics and Natural Computation, 2021We introduce a category of fuzzy convergence groups, FCONVGRP a subcategory of the category of fuzzy convergence spaces, FCONV. Viewing [Formula: see text] as a complete Heyting algebra, we prove that the category of [Formula: see text]-tolerance groups, [Formula: see text]-TOLGRP is isomorphic to a subcategory of FCONVGRP.

First, summarizing his paper ''On the concept of fuzzy point'' [Fuzzy Sets Syst. 18, 159-172 (1986; Zbl 0606.03014)], the author shows that a ''good definition of fuzzy point'' is impossible if one wants \(\in\) to be a nonfuzzy relation between fuzzy points and fuzzy subsets.

Fuzzy measures and convergence
Fuzzy Sets and Systems, 1988Several theorems have been proved, e.g. by Ralescu, Ralescu and Adams, Puri and Ralescu, and Klement, in order to unify the approach to uncertainty of both statistical and fuzzy origin. The present paper is motivated by the same instances and deals with some extensions of the measure-theoretical bases o the unit ball in \(\Lambda_ 0\). Again, the ``non-

If \(S=S(n)\), \(n\in D\), is a fuzzy net and e is a point in X then a set \({\mathcal G}=\{(S,E)\}\) is called a convergence class for X if some conditions are satisfied. A characterization of fuzzy topology in a nonempty set is given. In particular, for each fuzzy convergence class \({\mathcal G}\) for X a map C: \(I^ X\to I^ X\) is induced as ...

On the Convergence of the Fuzzy Clustering Algorithm “Fuzzy ISODATA”
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1986AbstractIn der vorliegenden Arbeit wird für den unscharfen Partitionierungsalgorithmus “Fuzzy ISODATA” gezeigt, daß ausgehend von beliebigem Startpunkt jeder Häufungspunkt der generierten Folge ein stationärer Punkt des erweiterten, Quadratischen‐Fehlersummen‐Funktionals ist, welches als Partitionierungskriterium dient.
