http://www.ijaha.org/article_46033_4638.html
Algebraic hypoerstructures have been developed not only from the theoretical point of view, but also for the applications they have in various elds, [2] - [25], [17][21]. The determination of the Fuzzy Grade of a hypergroup (or more generally of a hypergroupoid) is one of the most prominent problems of the theme: Connections between Fuzzy Sets and Hyperstructures. It has been considered for the rst time by Corsini [3] in 1993 and it has been studied also in the following years by several scientists in Romania, Greece, Italy, Iran, Canada, [1], [3], [4] - [27], [22] - [26]. In this paper one has studied the Fuzzy Grade in two situations: for hypergroups of transformations of a set A, in the case |A|= 2 and for hypergroups associated with ordered sets of cardinality m such that 2≤ m ≤ 10 and m = 12.Wed, 30 Nov 2016 20:30:00 +0100TRANSPOSITION HYPERGROUPS WITH IDEMPOTENT IDENTITY

http://www.ijaha.org/article_40721_4638.html
The overall aim of this paper is to present an introduction to someof the results, methods and ideas about fundamental relations on algebraichyperstructures . Fundamental relations are special kind of strongly regularrelations and they are important in the theory of algebraic hyperstructures. Indeed, the main tools connecting the class of hyperstructures with theclassical algebraic structures are the fundamental relations .

http://www.ijaha.org/article_42056_4638.html
The path hyperoperation, associated with a given directed graph,was recently introduced as a generalization of the Corsini hyperoperation. Inthis paper we study properties of the path hyperoperation and of the relatedsimple path and common ancestry hyperoperations.Wed, 30 Nov 2016 20:30:00 +0100ON COMMUTATIVE HYPERRINGS

http://www.ijaha.org/article_42057_4638.html
Abstract. On the general Hv-Lie algebras we investigate several classes mainlywhen only the bracket is a hyperoperation. In the nite dimensional Lie algebrasand in the innite dimensional Kac-Moody Lie algebras, as well, the matrixrepresentation problem is introduced and studied. Finally we present thehyper-representation problem on non-square matrices using the helix-hopes.Examples are presented by using some general classes as the P-hopes and the∂-hopes.vWed, 30 Nov 2016 20:30:00 +0100THE UNIQUE SQUARE ROOT CONDITION FOR QUASI-ORDER HYPERGROUPS AND CONSTRUCTION OF A ...

http://www.ijaha.org/article_42058_4638.html
In this paper we propose an extension of the concept of reducibilityin a crisp hypergroup to the fuzzy case. The idea will be developed in twodirections: dening the reducibility in a fuzzy hypergroup and dening thefuzzy reducibility in a crisp hypergroup endowed with a fuzzy set.Wed, 30 Nov 2016 20:30:00 +0100ON H-STRUCTURES ASSOCIATED WITH BINARY RELATIONS

http://www.ijaha.org/article_42061_4638.html
Abstract. Starting by the modellization of social relations by Moreno, havingas mathematical tools binary matrices and graph theory, we propose some newmodels based on algebraic hyperstructures, fuzzy sets and fuzzy hyperstructures.One of the main ideas is that the social aggregations can be described asalgebraic hyperoperations. Another idea is that an algebraic hyperoperation,having many possible results, is useful to represent uncertainty on the resultof an aggregation between individuals. Moreover, the relations considered byMoreno can be usefully replaced by fuzzy relations that are more precise indescription of human relationships.Wed, 30 Nov 2016 20:30:00 +0100FUZZY BOOLEAN SUBHYPERALGEBRAS

http://www.ijaha.org/article_42062_4638.html
Motivated by properties of the Laplace transformation and certaintypes of ordinary dierential equations a number of single-valued structures ofoperators of specic types has so far been constructed. Also, hyperstructuresof a certain type have been constructed on these single-valued sets. In thispaper we aim at linking these hyperstructures by constructing homomorphismsbetween them.Wed, 30 Nov 2016 20:30:00 +0100ON CATEGORICAL CONNECTIONS OF HYPERRINGS AND RINGS VIA THE FUNDAMENTAL RELATION

http://www.ijaha.org/article_48556_4638.html
EL-hyperstructures are hyperstructures constructed from singlevaluedquasi-ordered semigroups. For some kinds of sets it is dicult to nd ameaningful single-valued associative operation which could be used as a basisfor constructing the EL-hyperstructure. In this paper we use the systematicapproach to dene it. We focus on multicomponent sets and briey mention the n-ary context of the construction.Wed, 30 Nov 2016 20:30:00 +0100GENERALIZED k; m-STEP FIBONACCI SEQUENCES AND MATRICES
http://www.ijaha.org/article_42063_4638.html
Abstract. For two given integers k; m and the nonnegative real constants c,i = 1; 2; : : : ; k, we introduce the generalized k; m-step Fibonacci sequence bypresenting a recursive formula that generates the n-th term as the sum of ksuccessive previous terms starting the sum at the m-th previous term. Thegeneralized k; m-Fibonacci matrices are dened, their characteristic polynomialsare presented and some bounds for the spectral radius and the modulus ofthe remaining eigenvalues of the matrices are discussed. A closed formula ofthe n-th term of generalized k; m-step Fibonacci sequence is given generalizingthe Binet' s formula. Two limiting properties of the sequence are presented.The limits are related to the spectral radius of the generalized k; m-Fibonaccimatrices.Wed, 30 Nov 2016 20:30:00 +0100HYPERSTRUCTURES IN QUESTIONNAIRES
http://www.ijaha.org/article_42064_4638.html
An application of hyperstructure theory on social sceince is presented.In social sciences when questionnaires are used, there is a new tool,the bar instead of Likert scale. The bar has been suggested by Vougiouklis& Vougiouklis in 2008, who have proposed the replacement of likert scales,usually used in questionnaires, with bar. This new tool, gives the opportunityto researchers to elaborate the questionnaires in dierent ways, depending onthe lled questionnaries and of course on the problem. We study these lledquestionnaires using hyperstructure theory. Moreover the lling questionnaireprocedure has been improved using computers. We developed a software thatuses the bar and saves automatically the results and also for lling faster thequestionnaire. The hyperstructure theory is being related with questionnairesand we study the obtained hyperstructures which are used as an organizeddevice of the problem and we focus on special problems.Wed, 30 Nov 2016 20:30:00 +0100s2- Hv(h\v)-STRUCTURES AND s2-Hyperstructures
