##### 1. On (σ, τ)-module extension Banach algebras

M. Fozouni

Volume 03, Issue 04 , Autumn 2014, Pages 185-194

##### Abstract
Let A be a Banach algebra and X be a Banach A-bimodule. In this paper, we defi ne a new product on $A\oplus X$ and generalize the module extension Banach algebras. We  obtain characterizations of Arens regularity, commutativity, semisimplity, and study the ideal structure and derivations of this ...  Read More

##### 2. Soft regular generalized b-closed sets in soft topological spaces

S. M. Al-Salem

Volume 03, Issue 04 , Autumn 2014, Pages 196-204

##### Abstract
The main purpose of this paper is to introduce and study new classes of soft closed sets like soft regular generalized b-closed sets in soft topological spaces (briefly soft rgb-closed set) Moreover, soft rg -closed, soft gpr-closed, soft gb-closed, soft gsp-closed, soft g$\alpha$-closed, ...  Read More

##### 3. OD-characterization of $U_3(9)$ and its group of automorphisms

P. Nosratpour

Volume 03, Issue 04 , Autumn 2014, Pages 205-209

##### Abstract
Let $L = U_3(9)$ be the simple projective unitary group in dimension 3 over a field  with 92 elements. In this article, we classify groups with the same order and degree pattern as an almost simple group related to $L$. Since $Aut(L)\equiv Z_4$ hence almost simple groups related to $L$ are ...  Read More

##### 4. On φ-Connes amenability of dual Banach algebras

A. Mahmoodi

Volume 03, Issue 04 , Autumn 2014, Pages 211-217

##### Abstract
Let φ be a w-continuous homomorphism from a dual Banach algebra to C. The notion of φ-Connes amenability is studied and some characterizations is given. A type of diagonal for dual Banach algebras is de ned. It is proved that the existence of such a diagonal is equivalent to φ-Connes ...  Read More

##### 5. Fixed point theorems for α-ψ-ϕ-contractive integral type mappings

Volume 03, Issue 04 , Autumn 2014, Pages 219-230

##### Abstract
In this paper, we introduce a new concept of α-ψ-ϕ-contractive integral type mappings and establish some new fixed point theorems in complete metric spaces.  Read More

##### 6. Steffensen method for solving nonlinear matrix equation $X+A^T X^{(-1)}A=Q$

A. Nazari; Kh. Sayehvand; M. Rostami

Volume 03, Issue 04 , Autumn 2014, Pages 231-247

##### Abstract
In this article we study Steffensen method to solve nonlinear matrix equation $X+A^T X^{(-1)}A=Q$, when $A$ is a normal matrix. We establish some conditions that generate a sequence of positive de nite matrices which converges to solution of this equation.  Read More
