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

J
Shamshiri
This study concerns the existence and multiplicity of positive weak solutions for a class ofsemilinear elliptic systems with nonlinear boundary conditions. Our results is depending onthe local minimization method on the Nehari manifold and some variational techniques. Alsoby using Mountain Pass Lemma, we establish the existence of at least one solution withpositive energy.

Subcategories of topological algebras
V
Gompa
In addition to exploring constructions and properties of limits and colimits in categories of topologicalalgebras, we study special subcategories of topological algebras and their properties. In particular, undercertain conditions, reflective subcategories when paired with topological structures give rise to reflectivesubcategories and epireflective subcategories give rise to epireflective subcategories.

Common fixed point results on vector metric spaces
G
Soleimani Rad
I
Altun
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.

A note on quasi irresolute topological groups
T
Oner
A
Ozek
In this study, we investigate the further properties of quasi irresolute topological groupsdened in [20]. We show that if a group homomorphism f between quasi irresolute topologicalgroups is irresolute at eG, then f is irresolute on G. Later we prove that in a semi-connectedquasi irresolute topological group (G; ; ), if V is any symmetric semi-open neighborhood ofeG, then G is generated by V . Moreover it is proven that a subgroup H of a quasi irresolutetopological group (G; ; ) is semi-discrete if and only if it has a semi-isolated point.

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 ofspaces with other corresponding types are established. Moreover, several ofits basic and important properties are discussed.

pairwise quasi H-closed
pairwise almost co-compact

In this paper, we consider the finitely 2-generated groups K(s,l) and G_m as follows:K(s,l) = ;G_m = and find the explicit formulas for the probability of having nth-roots for them. Also weinvestigate integers n for which, these groups are n-central.

Recognition by prime graph of the almost simple group PGL(2, 25)
A
Mahmoudifar
Throughout this paper, every groups are finite. The prime graph of a group G is denotedby τ(G). Also G is called recognizable by prime graph if for every finite group H withτ(H) = τ(G), we conclude that G = H. Until now, it is proved that if k is an odd numberand p is an odd prime number, then PGL(2; pk) is recognizable by prime graph. So if k iseven, the recognition by prime graph of PGL(2; pk), where p is an odd prime number, is anopen problem. In this paper, we generalize this result and we prove that the almost simplegroup PGL(2; 25) is recognizable by prime graph.
