##### 1. ZERO-DIVISOR GRAPH OF THE RINGS OF REAL MEASURABLE FUNCTIONS WITH THE MEASURES

*Volume 9, Issue 2 , Winter and Spring 2022, Pages 175-192*

#####
**Abstract **

Let $M(X, \mathcal{A}, \mu)$ be the ring of real-valued measurable functionson a measurable space $(X, \mathcal{A})$ with measure $\mu$.In this paper, we study the zero-divisor graph of $M(X, \mathcal{A}, \mu)$,denoted by $\Gamma(M(X, \mathcal{A}, \mu))$.We give the relationships among graph properties ...

##### 2. DISTANCE LAPLACIAN SPECTRUM OF THE COMMUTING GRAPH OF FINITE CA-GROUPS

*Volume 9, Issue 2 , Winter and Spring 2022, Pages 193-201*

#####
**Abstract **

The commuting graph of a finite group $G$, $\mathcal{C}(G)$, is a simple graph with vertex set $G$ in which two vertices $x$ and $y$ are adjacent if and only if $xy = yx$. The aim of this paper is to compute the distance Laplacian spectrum and the distance Laplacian energy of the commuting graph of $CA$-groups.

##### 3. ANNIHILATING-IDEAL GRAPH OF C(X)

*Volume 9, Issue 2 , Winter and Spring 2022, Pages 203-217*

#####
**Abstract **

In this article the annihilating-ideal graph of the ring C(X) is studied. We have tried to associate the graph properties of AG(X), the ring properties of C(X) and the topological properties of X. It is shown that X has an isolated point if and only if R is a direct summand of C(X) and this happens if ...

##### 4. TOPICS ON CONTINUOUS INVERSE ALGEBRAS

*Volume 9, Issue 2 , Winter and Spring 2022, Pages 219-227*

#####
**Abstract **

In this paper, we first provide some counterexamples and derive some new results concerning the usual and singular spec- trum of an element in continuous inverse algebras. Then we continue our investigation about the characterizations of multiplicative linear maps and their related results in these algebras.

##### 5. (7,K) GIRTH-8 QC-LDPC CODES WITH AN EXPLICIT CONSTRUCTION

*Volume 9, Issue 2 , Winter and Spring 2022, Pages 229-239*

#####
**Abstract **

Recently, for each row weight $K$ and column-weight $J$, $3\le J< K$, several classes of $(J,K)$ quasi-cyclic (QC) low-density parity-check (LDPC) codes with girth 8 have been constructed explicitly such that their corresponding lower-bounds on the size of circulant permutation matrices (CPMs) have ...

##### 6. Geometric Hypergroups

*Volume 9, Issue 2 , Winter and Spring 2022, Pages 241-257*

#####
**Abstract **

The aim of this paper is to extend the notion of geometric groups to geometric hypergroups and to investigate the interaction between algebraic and geometric properties of hypergroups. In this regard, we first define a metric structure on hypergroups via word metric and present some examples on it by ...

##### 7. SOME INEQUALITIES FOR POLYNILPOTENT MULTIPLIER OF POWERFULL p-GROUPS

*Volume 9, Issue 2 , Winter and Spring 2022, Pages 259-265*

#####
**Abstract **

In this paper we present some inequalities for the order, the exponent, and the number of generators of the polynilpotent multiplier, the Baer invariant with respect to the variety of polynilpotent groups of class row (c_1; · · · ; c_t) of a powerful p-group.Our results extend some ...

##### 8. ON SOME TOTAL GRAPHS ON FINITE RINGS

*Volume 9, Issue 2 , Winter and Spring 2022, Pages 267-280*

#####
**Abstract **

We give a decomposition of total graphs on some finite commutative rings R = Zm, where the set of zero-divisors of R is not an ideal. In particular, we study the total graph T((Z2npm))where p is a prime and m and n are positive integers and investigate some graph theoretical properties with some ...

##### 9. A METRIC-LIKE TOPOLOGY ON BL-ALGEBRAS

*Volume 9, Issue 2 , Winter and Spring 2022, Pages 281-298*

#####
**Abstract **

This paper is devoted to introduce a topology on BL-algebras, makes them semitopological algebras. For any BL-algebra $\mathcal{L}=(L, \wedge, \vee, *, \too , 0, 1)$, the introduced topology is defined by a distance-like function between elements of $L$ which is defined by $a \leftrightarrow b=(a\too ...

##### 10. ON DERIVATIONS OF PSEUDO-BL ALGEBRA

*Volume 9, Issue 2 , Winter and Spring 2022, Pages 299-322*

#####
**Abstract **

Pseudo-BL algebras are a natural generalization of BL-algebras and of pseudo-MV algebras.In this paper the notions of five different types of derivations on a \pbl\ as generalizations of derivations of a BL-algebra are introduced. Moreover, as an extension of derivations of a \pbl , the notions of $(\varphi ...

##### 11. FINITENESS PROPERTIES OF FORMAL LOCAL COHOMOLOGY MODULES

*Volume 9, Issue 2 , Winter and Spring 2022, Pages 323-333*

#####
**Abstract **

In this paper, we investigate some properties of top formal localcohomology FdimM=aMa (M). Among other things, we determine AttR(FdimM=aMa (M)),in the case that FdimM=aMa (M) is an artinian module. Also we show that FdimM=aMa (M)is artinian if and only if it is minimax..
