FUZZY ORDERED SETS AND DUALITY FOR FINITE FUZZY DISTRIBUTIVE LATTICES

Abdelaziz Amroune; Bijan Davvaz

Volume 8, Issue 5 , September and October 2011, Pages 1-12

Abstract
  The starting point of this paper is given by Priestley’s papers, where a theory of representation of distributive lattices is presented. The purpose of this paper is to develop a representation theory of fuzzy distributive lattices in the finite case. In this way, some results of Priestley’s ...  Read More

ON ALGEBRAIC AND COALGEBRAIC CATEGORIES OF VARIETY-BASED TOPOLOGICAL SYSTEMS

Sergey A. Solovyov

Volume 8, Issue 5 , September and October 2011, Pages 13-30

Abstract
  Motivated by the recent study on categorical properties of latticevalued topology, the paper considers a generalization of the notion of topological system introduced by S. Vickers, providing an algebraic and a coalgebraic category of the new structures. As a result, the nature of the category   TopSys   of ...  Read More

ALGEBRAIC GENERATIONS OF SOME FUZZY POWERSET OPERATORS

Volume 8, Issue 5 , September and October 2011, Pages 31-58

Abstract
  In this paper, let $L$ be a completeresiduated lattice, and let {\bf Set} denote the category of setsand mappings, $LF$-{\bf Pos} denote the category of $LF$-posets and$LF$-monotone mappings, and $LF$-{\bf CSLat}$(\sqcup)$, $LF$-{\bfCSLat}$(\sqcap)$ denote the category of $LF$-completelattices and $LF$-join-preserving ...  Read More

NEW DIRECTION IN FUZZY TREE AUTOMATA

S. Moghari; M. M. Zahedi; R. Ameri

Volume 8, Issue 5 , September and October 2011, Pages 59-68

Abstract
  In this paper, our focus of attention is the proper propagationof fuzzy degrees in determinization of $Nondeterministic$ $Fuzzy$$Finite$ $Tree$ $Automata$ (NFFTA). Initially, two determinizationmethods are introduced which have some limitations (one inbehavior preserving and other in type of fuzzy operations). ...  Read More

THE CONNECTION BETWEEN SOME EQUIVALENCE RELATIONS ON FUZZY SUBGROUPS

Ali Iranmanesh; Hossein Naraghi

Volume 8, Issue 5 , September and October 2011, Pages 69-80

Abstract
  This paper, deals with some equivalence relations in fuzzy subgroups. Further the probability of commuting two fuzzy subgroups of some finite abelian groups is defined.  Read More

A NEW WAY TO FUZZY h-IDEALS OF HEMIRINGS

Yunqiang Yin; Jianming Zhan; Xiaokun Huang

Volume 8, Issue 5 , September and October 2011, Pages 81-101

Abstract
  By means of a kind of new idea, we consider  the $(\in,\ivq)$-fuzzy$h$-ideals of a hemiring.  First, the concepts of $(\in,\ivq)$-fuzzyleft(right) $h$-ideals of a hemiring are provided and some relatedproperties are investigated. Then, a kind  of quotient hemiring  ofa hemiring by ...  Read More

FUZZY REFLEXIVITY OF FELBIN'S TYPE FUZZY NORMED LINEAR SPACES AND FIXED POINT THEOREMS IN SUCH SPACES

T. Bag; S. K. Samanta

Volume 8, Issue 5 , September and October 2011, Pages 103-115

Abstract
  An idea of fuzzy reexivity of Felbin's type fuzzy normed linear spaces is introduced and its properties are studied. Concept of fuzzy uniform normal structure is given and using the geometric properties of this concept xed point theorems are proved in fuzzy normed linear spaces.  Read More

ON FELBIN’S-TYPE FUZZY NORMED LINEAR SPACES AND FUZZY BOUNDED OPERATORS

Mohammad Janfada; Hamid Baghani; Omid Baghani

Volume 8, Issue 5 , September and October 2011, Pages 117-130

Abstract
  In this note, we aim to present some properties of the space of all weakly fuzzy bounded linear operators, with the Bag and Samanta’s operator norm on Felbin’s-type fuzzy normed spaces. In particular, the completeness of this space is studied. By some counterexamples, it is shown that ...  Read More

GRADUAL NORMED LINEAR SPACE

I. Sadeqi; F. Y. Azari

Volume 8, Issue 5 , September and October 2011, Pages 131-139

Abstract
  In this paper, the gradual real numbers are considered and the notion of the gradual normed linear space is given. Also some topological properties of such spaces are studied, and it is shown that the gradual normed linear space is a locally convex space, in classical sense. So the results in locally convex ...  Read More

$\psi -$weak Contractions in Fuzzy Metric Spaces

Mujahid Abbas; M. Imdad; D. Gopal

Volume 8, Issue 5 , September and October 2011, Pages 141-148

Abstract
  In this paper, the notion of $\psi -$weak contraction \cite{Rhoades} isextended to fuzzy metric spaces. The existence of common fixed points fortwo mappings is established where one mapping is $\psi -$weak contractionwith respect to another mapping on a fuzzy metric space. Our resultgeneralizes a result ...  Read More

Volume 8, Issue 5 , September and October 2011, Pages 149-166

Abstract
  In this paper we investigate the algebraic properties of dimension of fuzzy hypervector spaces. Also, we prove that two isomorphic fuzzy hypervector spaces have the same dimension.  Read More
