##### 1. A COVERING PROPERTY IN PRINCIPAL BUNDLES

*Volume 5, Issue 2 , Winter and Spring 2018, Pages 91-98*

#####
**Abstract **

Let $p:X\lo B$ be a locally trivial principal G-bundle and $\wt{p}:\wt{X}\lo B$ be a locally trivial principal $\wt{G}$-bundle. In this paper, by using the structure of principal bundles according to transition functions, we show that $\wt{G}$ is a covering group of $G$ if and only if $\wt{X}$ is a covering ...

**Abstract **

Abstract. Let m; n ≥ 2 be two positive integers, R a commutative ring with identity and M a unitary R-module. A proper submodule P of M is an (n 1; n)-Φm-prime ((n 1; n)-weakly prime) submodule if a1; : : : ; an1 2 R and x 2 M together with a1 : : : an1x 2 Pn(P : M)m1P ...

##### 3. SEQUENTIALLY COMPACT S-ACTS

*Volume 5, Issue 2 , Winter and Spring 2018, Pages 111-125*

#####
**Abstract **

The investigation of equational compactness was initiated by Banaschewski and Nelson. They proved that pure injectivity is equivalent to equational compactness. Here we define the so called sequentially compact acts over semigroups and study ...

##### 4. TOTAL DOMINATION POLYNOMIAL OF GRAPHS FROM PRIMARY SUBGRAPHS

*Volume 5, Issue 2 , Winter and Spring 2018, Pages 127-138*

#####
**Abstract **

Let $G = (V, E)$ be a simple graph of order $n$. The total dominating set is a subset $D$ of $V$ that every vertex of $V$ is adjacent to some vertices of $D$. The total domination number of $G$ is equal to minimum cardinality of total dominating set in $G$ and denoted by $\gamma_t(G)$. The total domination ...

##### 5. ON p-NILPOTENCY OF FINITE GROUPS WITH SS-NORMAL SUBGROUPS

*Volume 5, Issue 2 , Winter and Spring 2018, Pages 139-148*

#####
**Abstract **

Abstract. A subgroup H of a group G is said to be SS-embeddedin G if there exists a normal subgroup T of G such that HT issubnormal in G and H \ T ≤ H sG , where H sG is the maximal s-permutable subgroup of G contained in H. We say that a subgroupH is an SS-normal subgroup in G if there exists ...

##### 6. INTERSECTION OF ESSENTIAL IDEALS IN THE RING OF REAL-VALUED CONTINUOUS FUNCTIONS ON A FRAME

*Volume 5, Issue 2 , Winter and Spring 2018, Pages 149-161*

#####
**Abstract **

A frame $L$ is called {\it coz-dense} if $\Sigma_{coz(\alpha)}=\emptyset$ implies $\alpha=\mathbf 0$. Let $\mathcal RL$ be the ring of real-valued continuous functions on a coz-dense and completely regular frame $L$. We present a description of the socle of the ring $\mathcal RL$ based on minimal ideals ...
