##### 1. Existence and multiplicity of positive solutions for a class of semilinear elliptic system with nonlinear boundary conditions

*Volume 05, Issue 01 , Winter 2016, Pages 1-13*

#####
**Abstract **

This study concerns the existence and multiplicity of positive weak solutions for a class of semilinear elliptic systems with nonlinear boundary conditions. Our results is depending on the local minimization method on the Nehari manifold and some variational techniques. Also, by using ...

##### 2. Subcategories of topological algebras

*Volume 05, Issue 01 , Winter 2016, Pages 15-28*

#####
**Abstract **

In addition to exploring constructions and properties of limits and colimits in categories of topological algebras, we study special subcategories of topological algebras and their properties. In particular, under certain conditions, reflective subcategories when paired with topological structures ...

##### 3. Common fixed point results on vector metric spaces

*Volume 05, Issue 01 , Winter 2016, Pages 29-39*

#####
**Abstract **

In this paper we consider the so called a vector metric space, which is a generalization of metric space, where the metric is Riesz space valued. We prove some common fixed point theorems for three mappings in this space. Obtained results extend and generalize well-known comparable results in the literature.

##### 4. A note on quasi irresolute topological groups

*Volume 05, Issue 01 , Winter 2016, Pages 41-46*

#####
**Abstract **

In this study, we investigate the further properties of quasi irresolute topological groups defined in [20]. We show that if a group homomorphism f between quasi irresolute topological groups is irresolute at $e_G$, then $f$ is irresolute on $G$. Later we prove that in a semi-connected quasi ...

##### 5. F-Closedness in Bitopological Spaces

*Volume 05, Issue 01 , Winter 2016, Pages 47-53*

#####
**Abstract **

The purpose of this paper is to introduce the concept of pairwise F-closedness in bitopological spaces. This space contains both of pairwise strongcompactness and pairwise S-closedness and contained in pairwise quasi H-closedness. The characteristics and relationships concerning this new class of spaces ...

##### 6. Probability of having $n^{th}$-roots and n-centrality of two classes of groups

*Volume 05, Issue 01 , Winter 2016, Pages 55-62*

#####
**Abstract **

In this paper, we consider the finitely 2-generated groups $K(s,l)$ and $G_m$ as follows:$$K(s,l)=\langle a,b|ab^s=b^la, ba^s=a^lb\rangle,\\G_m=\langle a,b|a^m=b^m=1, {[a,b]}^a=[a,b], {[a,b]}^b=[a,b]\rangle$$ and find the explicit formulas for the probability of having nth-roots for them. Also, ...
