FUZZY HV -SUBSTRUCTURES IN A TWO DIMENSIONAL EUCLIDEAN VECTOR SPACE

Achilles Dramalidis; Thomas Vougiouklis

Volume 6, Issue 4 , November and December 2009, Pages 1-9

Abstract
  In this paper, we study fuzzy substructures in connection withHv-structures. The original idea comes from geometry, especially from thetwo dimensional Euclidean vector space. Using parameters, we obtain a largenumber of hyperstructures of the group-like or ring-like types. We connect,also, the mentioned ...  Read More

FUZZY PSEUDOTOPOLOGICAL HYPERGROUPOIDS

Irina Cristea; Sarka Hoskova

Volume 6, Issue 4 , November and December 2009, Pages 11-19

Abstract
  On a hypergroupoid one can define a topology such that the hyperoperationis pseudocontinuous or continuous. In this paper we extend thisconcepts to the fuzzy case. We give a connection between the classical and thefuzzy (pseudo)continuous hyperoperations.  Read More

FUZZY HYPERIDEALS IN TERNARY SEMIHYPERRINGS

Bijan Davvaz

Volume 6, Issue 4 , November and December 2009, Pages 21-36

Abstract
  In a ternary semihyperring, addition is a hyperoperation and multiplicationis a ternary operation. Indeed, the notion of ternary semihyperringsis a generalization of semirings. Our main purpose of this paper is to introducethe notions of fuzzy hyperideal and fuzzy bi-hyperideal in ternary semihyperrings.We ...  Read More

T-FUZZY CONGRUENCES AND T-FUZZY FILTERS OF A BL-ALGEBRA

Rajab Ali Borzooei; Mahmood Bakhshi

Volume 6, Issue 4 , November and December 2009, Pages 37-47

Abstract
  In this note, we introduce the concept of a fuzzy filter of a BLalgebra,with respect to a t-norm briefly, T-fuzzy filters, and give some relatedresults. In particular, we prove Representation Theorem in BL-algebras. Thenwe generalize the notion of a fuzzy congruence (in a BL-algebra) was definedby Lianzhen ...  Read More

ON SOME STRUCTURES OF FUZZY NUMBERS

Antonio Maturo

Volume 6, Issue 4 , November and December 2009, Pages 49-59

Abstract
  The operations in the set of fuzzy numbers are usually obtained bythe Zadeh extension principle. But these definitions can have some disadvantagesfor the applications both by an algebraic point of view and by practicalaspects. In fact the Zadeh multiplication is not distributive with respect tothe addition, ...  Read More

SPECTRUM OF PRIME FUZZY HYPERIDEALS

R. Ameri; R. Mahjoob

Volume 6, Issue 4 , November and December 2009, Pages 61-72

Abstract
  Let R be a commutative hyperring with identity. We introduceand study prime fuzzy hyperideals of R. We investigate the Zariski topologyon FHspec(R), the spectrum of prime fuzzy hyperideals of R.  Read More

SOME PROPERTIES OF T-FUZZY GENERALIZED SUBGROUPS

Mahmood Bakhshi; Rajab Ali Borzooei

Volume 6, Issue 4 , November and December 2009, Pages 73-87

Abstract
  In this paper, we deal with Molaei’s generalized groups. We definethe notion of a fuzzy generalized subgroup with respect to a t-norm (orT-fuzzy generalized subgroup) and give some related properties. Especially,we state and prove the Representation Theorem for these fuzzy generalizedsubgroups. ...  Read More
