EXTENSION OF FUZZY CONTRACTION MAPPINGS

H VOSOUGHI; S. J Hosseini Ghoncheh

Volume 9, Issue 5 , November and December 2012, Pages 1-6

Abstract
  In a fuzzy metric space (X;M; *), where * is a continuous t-norm,a locally fuzzy contraction mapping is de ned. It is proved that any locally fuzzy contraction mapping is a global fuzzy contractive. Also, if f satis es the locally fuzzy contractivity condition then it satis es the global fuzzy contrac-tivity ...  Read More

(T,S)-BASED INTERVAL-VALUED INTUITIONISTIC FUZZY COMPOSITION MATRIX AND ITS APPLICATION FOR CLUSTERING

H. L HUANG

Volume 9, Issue 5 , November and December 2012, Pages 7-19

Abstract
  In this paper, the notions of $(T,S)$-composition matrix and$(T,S)$-interval-valued intuitionistic fuzzy equivalence matrix areintroduced where $(T,S)$ is a dual pair of triangular module. Theyare the generalization of composition matrix and interval-valuedintuitionistic fuzzy equivalence matrix. Furthermore, ...  Read More

A FIXED POINT APPROACH TO THE INTUITIONISTIC FUZZY STABILITY OF QUINTIC AND SEXTIC FUNCTIONAL EQUATIONS

Tian Zhou Xu; Matina John Rassias; Wan Xin Xu

Volume 9, Issue 5 , November and December 2012, Pages 21-40

Abstract
  The fixed point alternative methods are implemented to giveHyers-Ulam  stability for  the quintic functional equation $ f(x+3y)- 5f(x+2y) + 10 f(x+y)- 10f(x)+ 5f(x-y) - f(x-2y) = 120f(y)$ and thesextic functional equation $f(x+3y) - 6f(x+2y) + 15 f(x+y)- 20f(x)+15f(x-y) - 6f(x-2y)+f(x-3y) = ...  Read More

Halis Aygun; Vildan Cetkin; S. E. Abbas

Volume 9, Issue 5 , November and December 2012, Pages 41-62

Abstract
  The aim of this paper is to introduce $(L,M)$-fuzzy closurestructure where $L$ and $M$ are strictly two-sided, commutativequantales. Firstly, we define $(L,M)$-fuzzy closure spaces and getsome relations between $(L,M)$-double fuzzy topological spaces and$(L,M)$-fuzzy closure spaces. Then, we introduce ...  Read More

A NOTE ON INTUITIONISTIC FUZZY MAPPINGS

Yong-hong Shen; Fa-xing Wang; Wei Chen

Volume 9, Issue 5 , November and December 2012, Pages 63-76

Abstract
  In this paper, the concept of intuitionistic fuzzy mapping as a generalization of fuzzy mapping is presented, and its' relationship with intuitionistic fuzzy relations is derived. Moreover, some basicoperations of intuitionistic fuzzy mappings are defined, hence we can conclude that all of intuitionistic ...  Read More

NEW TYPES OF FUZZY n-ARY SUBHYPERGROUPS OF AN n-ARY HYPERGROUP

Yunqiang Yin; Jianming Zhan; Bijan Davvaz

Volume 9, Issue 5 , November and December 2012, Pages 105-124

Abstract
  In this paper, the new notions of ``belongingness ($in_{gamma}$)"and ``quasi-coincidence ($q_delta$)"  of a fuzzy point with a fuzzyset are  introduced. By means of this new idea, the  concept of$(alpha,beta)$-fuzzy $n$-ary subhypergroup of an $n$-aryhypergroup is given, where $alpha,betain{in_{gamma}, q_{delta},in_{gamma}wedge ...  Read More
