##### ON THE SPECTRUM OF DERANGEMENT GRAPHS OF ORDER A PRODUCT OF THREE PRIMES

*Volume 6, Issue 2 , January 2019, Pages 81-89*

#####
**Abstract **

A permutation with no fixed points is called a derangement. The subset $\mathcal{D}$ of a permutation group is derangement if all elements of $\mathcal{D}$ are derangement. Let $G$ be a permutation group, a derangementgraph is one with vertex set $G$ and derangement set $\mathcal{D}$ as connecting ...

##### On $\alpha $-semi-Short Modules

*Volume 6, Issue 2 , January 2019, Pages 91-99*

#####
**Abstract **

We introduce and study the concept of $\alpha $-semi short modules. Using this concept we extend some of the basic results of $\alpha $-short modules to $\alpha $-semi short modules. We observe that if $M$ is an $\alpha $-semi short module then the dual perfect dimension of $M$ is $\alpha $ ...

##### ON SEMI MAXIMAL FILTERS IN BL-ALGEBRAS

*Volume 6, Issue 2 , January 2019, Pages 101-116*

#####
**Abstract **

In this paper, first we study the semi maximal filters in linear $BL$-algebras and we prove that any semi maximal filter is a primary filter. Then, we investigate the radical of semi maximal filters in $BL$-algebras. Moreover, we determine the relationship between this filters and other types of filters ...

##### ON STRONGLY ASSOCIATIVE HYPERRINGS

*Volume 6, Issue 2 , January 2019, Pages 117-130*

#####
**Abstract **

This paper generalizes the idea of strongly associative hyperoperation introduced in [7] to the class of hyperrings. We introduce and investigate hyperrings of type 1, type 2 and SDIS. Moreover, we study some examples of these hyperrings and give a new kind of hyperrings called totally hyperrings. ...

##### ON THE CAPACITY OF EILENBERG-MACLANE AND MOORE SPACES

*Volume 6, Issue 2 , January 2019, Pages 131-146*

#####
**Abstract **

K. Borsuk in 1979, at the Topological Conference in Moscow, introduced concept of the capacity of a compactum and asked some questions concerning properties of the capacity ofcompacta. In this paper, we give partial positive answers to three of these questions in some cases. In fact, by describing spaces ...

##### ON EQUALITY OF ABSOLUTE CENTRAL AND CLASS PRESERVING AUTOMORPHISMS OF FINITE p-GROUPS

*Volume 6, Issue 2 , January 2019, Pages 147-155*

#####
**Abstract **

Let $G$ be a finite non-abelian $p$-group and $L(G)$ denotes the absolute center of $G$. Also, let $\Aut^{L}(G)$ and $\Aut_c(G)$ denote the group of all absolute central and the class preserving automorphisms of $G$, respectively. In this paper, we give a necessary and sufficient condition for $G$ such ...
