bipolar fuzzy soft ordered hyperideals, bi-ideals and interior ideals of ordered Γ -hypersemigroups and discuss some properties

In this paper, we introduce the notion of direct sum of intuitionistic fuzzy submodules of G-module M and discuss some related properties. If B and C are intuitionistic fuzzy submodules of G-module M and G-module N respectively, then we extend the definition of intuitionistic fuzzy submodules B and C to formulate intuitionistic fuzzy submodules of the direct sum M ⊕ N. It is proved that the support of the direct sum of intuitionistic fuzzy submodules B and C is equal to the direct sum of supports of intuitionistic fuzzy submodules B and C. Also we analyze the direct sum of arbitrary family of intuitionistic fuzzy submodules and obtained some results. We also introduce the notion of decomposability and indecomposility of intuitionistic fuzzy G-modules and prove some results. 2010 AMS Classification: 03F55, 16D10

In this paper, we will introduce the notion of intuitionistic fuzzy G-module by defining the group action of G on the intuitionistic fuzzy set of Z-module M on which G-acts. We obtain the conditions when an intuitionistic fuzzy submodule be an intuitionstic fuzzy G-submodule. Some new notion like intuitionistic fuzzy prime submodule, intuitionistic fuzzy prime G-submodule, intuitionistic fuzzy semi prime submodule, intuitionistic fuzzy G-semi prime submodule, G-invariant intuitionistic fuzzy submodule and G-invariant intuitionistic fuzzy prime submodule of M will be introduced and studied. The homomorphic image and pre-image of intuitionistic fuzzy G-submodules, G-invariant intuitionistic fuzzy submodules and G-invariant intuitionistic fuzzy prime submodules of M will be established.

In this article, we introduce the notion of injectivity and quasi injectivity of an intuitionistic fuzzy G-module. We also establish a condition on finite dimensional G-modules for which an intuitionistic fuzzy G-module is injective with respect to another intuitionistic fuzzy G-module. We discuss the injectivity of an intuitionistic fuzzy G-module with respect to the quotient intuitionistic fuzzy G-module of another G-module. Some important properties of injectivity of intuitionistic fuzzy G-modules with regards to direct sum of intuitionistic fuzzy G-modules are also studied. A relationship between injectivity and quasi injectivity of intuitionistic fuzzy G-modules is also obtained.

ABSTRACT It has been established that the fuzzy sets do not hold the Complement laws of Boolean algebra. The aim of this article is to introduce and study a kind of family of fuzzy subsets of a finite set which holds the Complement laws. The complement operation has redefined for this purpose. Further, it has been established that the introduced fuzzy subsets can form Boolean lattice and also Boolean algebra. Keywords fuzzy subset, membership value, the complement operation, the complement laws, Boolean lattice, subsets of a fuzzy subset, fuzzy power set.

Result concerning various ideals in near rings (as defined by Yakabe, Chelvam and
Ganesan, Kim and Zhan and Xueling as well as some generalization thereof) that have been
established over the past three decays, will be discussed. These include the fuzzy ideals, fuzzy
quasi ideals and fuzzy bi-ideals in near rings. In this talk, we extend these notion to intuitionistic
fuzzy ideals, intuitionistic fuzzy quasi-ideals, intuitionistic fuzzy bi-ideals in near-rings. A relationship between various types of ideals has been established.

The concept of intuitionistic fuzzy G-modules and its properties including representation, reducibility and injectivity are already defined by the author et al. In this paper, we extend this idea to define semi-simplicity of intuitionistic fuzzy G-modules. The existence of a semi-simple intuitionistic fuzzy G-module for every finite dimensional G-module is proved and the relationships of semi-simplicity with other properties of intuitionistic fuzzy G-modules are also discussed.

In this paper, we redefine the definition of a fuzzy HX group and define a new algebraic structure of Q-fuzzy HX group and anti Q-fuzzy HX subgroup and some related properties are ivestigated. We establish the relation between Q-fuzzy HX group and anti Q-fuzzy HX group of a HX group . The purpose of this study is to implement the fuzzy set theory and group theory in anti Q-fuzzy HX subgroups.

Ranking of fuzzy numbers play an important role in decision making, optimization, forecasting etc. Fuzzy numbers must be ranked before an action is taken by a decision maker. In this paper, we propose a ranking algorithm for symmetric octagonal fuzzy numbers, which results in equality only when the numbers coincide. Also the ranking algorithm is verified for some reasonable properties of ordering of fuzzy numbers

In this paper, we introduce the notion of intuitionistic fuzzy superfluous (or small) submodule of a module and study some of their properties. We establish the condition of an intu-itionistic fuzzy submodule to be an intuitionistic fuzzy superfluous submodule. A relationship between superfluous submodule and the intuitionistic fuzzy superfluous submodule is derived. We also study the nature of intuitionistic fuzzy superfluous submodules under intuitionistic fuzzy direct sum. A relation regarding intuitionistic fuzzy superfluous submodule and intuitionistic fuzzy quotient module is established. It is shown that the well-known relation between the Jacobson radical and the superfluous submodules does not hold in case of intuitionistic fuzzy superfluous submodules.

The properties of homomorphism, isomorphism and automorphism of the fuzzy Boolean algebras have been investigated. Further, the ideal and filter of the fuzzy Boolean algebras have also been observed with their characteristics.

In this paper, we have constructed an intuitionistic fuzzy G-module with level cardinality (n + 1) on the Galois field GF(p n), and then proved that infinite many such intuitionistic fuzzy G-modules can be constructed on it. We have also proved that each such intuitionistic fuzzy G-module, admits a sequence of k intuitionistic fuzzy G-submodules, where k is the number of divisors of n. Further, we have also discussed intuitionistic fuzzy noetherian G-module on GF(p n). 2010 AMS Classification: 0355, 12E20

The importance of semigroups and their fuzzy subsystems is evident from their applications and significant role in several applied disciplines like computer sciences, control engineering, error-correcting codes and fuzzy automata theory. In this paper, we give generalizations of in-tuitionistic fuzzy interior ideals of semigroups and introduced the notions of intuitionistic fuzzy interior ideals of type (∈, ∈ ∨ q k) and (∈, ∈) of semi-groups. The important mile stone of the present paper is to link ordinary intuitionistic fuzzy interior ideals, (∈, ∈)-intuitionistic fuzzy interior ideals and (∈, ∈ ∨ q k)-intuitionistic fuzzy interior ideals. Moreover semigroups are characterized by the properties of these notions.

In the present manuscript, we introduce and study the notion of primary submodules as well as P-primary submodules of a module in the intuitionistic L-fuzzy environment. Apart from investigating basic properties of these submodules, we explore some foundational results analogous to corresponding submodules. A suitable characterization of intuitionistic L-fuzzy primary (P-primary) submodules in terms of primary (P-primary) submodules are presented.

The category theory deals with mathematical structures and relationships between them. Categories now appear in most branches of mathematics and in some areas of theoretical computer science and mathematical physics, and acting as a unifying notion. In this paper, we study the relationship between the category of groups and the category of intuitionistic fuzzy groups. We prove that the category of groups is a subcategory of category of intuitionistic fuzzy groups and that it is not an Abelian category. We establish a function β : Hom(A, B) → [0, 1] × [0, 1] on the set of all intuitionistic fuzzy homomorphisms between intuitionistic fuzzy groups A and B of groups G and H, respectively. We prove that β is a covariant functor from the category of groups to the category of intuitionistic fuzzy groups. Further, we show that the category of intuitionistic fuzzy groups is a top category by establishing a contravariant functor from the category of intuitionistic fuzzy groups to the lattices of all intuitionistic fuzzy groups.

Let R be a commutative ring with identity and M be an R-module. An intuitionistic L-fuzzy submodule (ILFSM) C of an intuitionistic L-fuzzy module A of R-module M , is called an intuitionistic L-fuzzy essential submodule in A, if C ∩ B = χ {θ} for any non-trivial ILFSM B of A. In this case we say that A is an essential extension of C. Also, if C has no proper essential extension in A, then C is called an intuitionistic L-fuzzy closed submodule in A. Further, for ILFSMs B, C of A, C is called complement of B in A if C is maximal with the property that B ∩ C = χ {θ}. We study these mentioned notations which are generalization of the notions of essential submodule, closed submodule and complement of a submodule in the intuitionistic L-fuzzy module theory. We prove many basic properties of both these concepts.

The main aim of this paper is to investigate the relationship between the characteristic of a ring and the order of an element in the intuitionistic fuzzy environment. We also characterise the term divisor of zero in a ring and study their connection with the ideal of the ring in the intuitionistic fuzzy setting. Some related results are also analyse.

In this paper some basic definitions of soft set
theory and fuzzy set theory are given. Then the concept of
fuzzy isomorphism theorems of idealistic soft gamma rings are

established and their proofs are given, respectively. Moreover,
several basic conclusions are given.

 It has been accepted that the set of all fuzzy subsets of a finite set cannot satisfy all the properties of Boolean algebra and the main cause is that for a fuzzy subset A and its complement A , neither AA   is the empty fuzzy subset, nor AA   is the universal fuzzy subset; where  and  represents the operations fuzzy union and fuzzy intersection respectively. Accordingly, the set of all the fuzzy subsets of a finite set have been accepted not to form a Boolean algebra. The fuzzy subsets of a finite set form a Boolean algebra if the proposed definition of the complement operation is considered. Since, this Boolean algebra is formed by the fuzzy subsets of a set we called this as a special fuzzy Boolean algebra. Throughout the article different aspects of the introduced special fuzzy Boolean algebra have been discussed.

In this paper, we study ordered hyperideals in ordered semihypergroups. Also, we study (m, n)-regular ordered semihypergroups in terms of ordered (m, n)-hyperideals. Furthermore, we obtain some ideal theoretic results in ordered semihypergroups.

In this talk, we study the concept of residual quotient of IF subsets of ring
and module and develop many properties out of these. Using the concept

annihilator of IF submodules, IF prime(primary) submodules and IF
prime(primary) decomposition.

In this paper we investigate the radical structure of an intuitionistic fuzzy polynomial ideal A x induced by an intuitionistic fuzzy ideal A of a ring and study its properties. Given an intuitionistic fuzzy ideal B of a ring R and a homomorphism f : R → R , we show that if f x : R[x] → R [x] is the induced homomorphism of f , that is, f x (n i=0 a i x i) = n i=0 (f (a i))x i , then f −1 x [(√ B) x ] = (f −1 (B)) x .

In this paper, we further study the theory of intuitionistic fuzzy rings and give some new concepts such as intuitionistic fuzzy ring with operators, intuitionistic fuzzy ideal with operators , intuitionistic fuzzy quotient ring with operators, etc. while their some elementary properties are discussed.
