The OP subgroup of a torsion-free LCA group

AliAkbar Alijani

Let $G$ be a locally compact abelian (LCA) group. We denote by $G_{o p}$ , the intersection of all open pure subgroups of $G$ , which we call the $O P$ subgroup of $G$ . In this paper,…

$* -$ open sets and $* -$ continuity in topological spaces

Aliakbar Alijani

In this paper, we study some properties of $* -$ open and $* -$ closed subsets of a space. The collection of all $* -$ open subsets of a space $X$ form a topology on $X$ which is denoted…

On TFU extensions in LCA groups

Aliakbar Alijani

Let $ℓ$ be the category of all locally compact abelian (LCA) groups. Let $G \in ℓ$ and $H \subseteq G$ . The first Ulm subgroup of $G$ is denoted by $G^{(1)}$ and the closure of…

On generalized $\unicode{x00A3}$-cotorsion LCA groups

Aliakbar Alijani

A locally compact abelian group $G$ is called a generalized $\unicode{x00A3}$-cotosion group if $G$ contains an open $\unicode{x00A3}$-cotosion subgroup $H$ such that $G / H$ is a co…

On T-locally compact spaces

Aliakbar Alijani

The aim of this paper is to introduce and give preliminary investigation of T-locally compact spaces. Locally compact and T-locally compact are independent of each other. Every Hau…

Circumferential Crack Modeling of Thin Cylindrical Shells in Modal Deformation

Ali Alijani, Olga Barrera, Stephane P. A. Bordas

An innovative technique, called conversion, is introduced to model circumferential cracks in thin cylindrical shells. The semi-analytical finite element method is applied to invest…

On t-extensions of abelian groups

Hussain Sahleh, Aliakbar Alijani

Let G and C be two discrete abelian groups. It is known that Pext(C,G) is a subgroup of Ext(C,G). In this paper, we introduce the t-extensions of G by C. We will show that the set…

Extensions of locally compact abelian, torsion-free groups by compact torsion abelian groups

Hossain Sahleh, Ali Akbar Alijani

Let $X$ be a compact torsion abelian group. In this paper, we show that an extension of $F_{p}$ by $X$ splits where $F_{p}$ is the p-adic number group and $p$ a prime number. Also,…

S-pure Extensions of Locally Compact Abelian Groups

Hossain Sahleh, Ali Akbar Alijani

In this paper, we introduce the concept and study some properties of an s-pure subgroup and a s-pure extension in the category of locally compact abelian groups.
