CONVERGENCE APPROACH SPACES AND APPROACH SPACES AS LATTICE-VALUED CONVERGENCE SPACES
Volume 9, Issue 4 , September and October 2012, Pages 1-16
Abstract
We show that the category of convergence approach spaces is a simultaneously reective and coreective subcategory of the category of latticevalued limit spaces. Further we study the preservation of diagonal conditions, which characterize approach spaces. It is shown that the category of preapproach spaces ...

Volume 9, Issue 4 , September and October 2012, Pages 17-30
Abstract
The existing Data Envelopment Analysis models for evaluating the relative eciency of a set of decision making units by using various inputs to produce various outputs are limited to crisp data in crisp production possibility set. In this paper, rst of all the production possibility set is extended to ... Read MoreCLASSIFYING FUZZY SUBGROUPS OF FINITE NONABELIAN GROUPS
Volume 9, Issue 4 , September and October 2012, Pages 31-41
Abstract
In this paper a rst step in classifying the fuzzy subgroups of a nite nonabelian group is made. We develop a general method to count the number of distinct fuzzy subgroups of such groups. Explicit formulas are obtained in the particular case of dihedral groups. Read MoreSOME FIXED POINT THEOREMS IN LOCALLY CONVEX TOPOLOGY GENERATED BY FUZZY N-NORMED SPACES
Volume 9, Issue 4 , September and October 2012, Pages 43-54
Abstract
The main purpose of this paper is to study the existence of a fixed point in locally convex topology generated by fuzzy n-normed spaces.We prove our main results, a fixed point theorem for a self mapping and acommon xed point theorem for a pair of weakly compatible mappings inlocally convex topology ...

Volume 9, Issue 4 , September and October 2012, Pages 55-70
Abstract
The purpose of this paper is to study matrix hemiring $S_{2}$ via fuzzy subsets and fuzzy $h$-ideals. Read MoreATANASSOV'S INTUITIONISTIC FUZZY GRADE OF I.P.S. HYPERGROUPS OF ORDER LESS THAN OR EQUAL TO 6
Volume 9, Issue 4 , September and October 2012, Pages 71-97
Abstract
In this paper we determine the sequences of join spaces and Atanassov's intuitionistic fuzzy sets associated with all i.p.s. hypergroups of order less than or equal to 6, focusing on the calculation of their lengths. Read MoreMore General Forms of $(alpha, beta )$-fuzzy Ideals of Ordered Semigroups
Volume 9, Issue 4 , September and October 2012, Pages 99-113
Abstract
This paper consider the general forms of $(alpha,beta)$-fuzzyleft ideals (right ideals, bi-ideals, interior ideals) of an orderedsemigroup, where$alpha,betain{in_{gamma},q_{delta},in_{gamma}wedgeq_{delta}, in_{gamma}vee q_{delta}}$ and $alphaneqin_{gamma}wedge q_{delta}$. Special attention ... Read MoreL-FUZZIFYING TOPOLOGICAL GROUPS
Volume 9, Issue 4 , September and October 2012, Pages 115-132
Abstract
The main purpose of this paper is to introduce a concept of$L$-fuzzifying topological groups (here $L$ is a completelydistributive lattice) and discuss some of their basic properties andthe structures. We prove that its corresponding $L$-fuzzifyingneighborhood structure is translation invariant. A characterizationof ... Read MoreFUZZY INTEGRAL OF MEASURABLE MULTIFUNCTIONS
Volume 9, Issue 4 , September and October 2012, Pages 133-140
Abstract
We study a fuzzy type integral for measurable multifunctions with respect to a fuzzy measure. Some classical properties and convergence theorems are presented. Read MoreON THE FUZZY DIMENSIONS OF FUZZY VECTOR SPACES
Volume 9, Issue 4 , September and October 2012, Pages 141-150
Abstract
In this paper, rstly, it is proved that, for a fuzzy vector space, the set of its fuzzy bases de ned by Shi and Huang, is equivalent to the family of its bases de ned by P. Lubczonok. Secondly, for two fuzzy vector spaces, it is proved that they are isomorphic if and only if they have the same fuzzy ... Read MoreON COMPACTNESS AND G-COMPLETENESS IN FUZZY METRIC SPACES
