##### 1. On the commuting graph of non-commutative rings of order $p^nq$

*Volume 03, Issue 01 , Winter 2014, Pages 1-6*

#####
**Abstract **

Let $R$ be a non-commutative ring with unity. The commuting graph of $R$ denoted by $\Gamma(R)$, is a graph with vertex set $R\Z(R)$ and two vertices $a$ and $b$ are adjacent iff $ab=ba$. In this paper, we consider the commuting graph of non-commutative rings of order pq and $p^2q$ with ...

##### 2. A note on the convergence of the Zakharov-Kuznetsov equation by homotopy analysis method

*Volume 03, Issue 01 , Winter 2014, Pages 7-13*

#####
**Abstract **

In this paper, the convergence of Zakharov-Kuznetsov (ZK) equation by homotopy analysis method (HAM) is investigated. A theorem is proved to guarantee the convergence of HAM and to nd the series solution of this equation via a reliable algorithm.

##### 3. On the superstability of a special derivation

*Volume 03, Issue 01 , Winter 2014, Pages 15-22*

#####
**Abstract **

The aim of this paper is to show that under some mild conditions a functional equation of multiplicative $(\alpha,\beta)$-derivation is superstable on standard operator algebras. Furthermore, we prove that this generalized derivation can be a continuous and an inner $(\alpha,\beta)$-derivation.

##### 4. Positive solution of non-square fully Fuzzy linear system of equation in general form using least square method

*Volume 03, Issue 01 , Winter 2014, Pages 23-33*

#####
**Abstract **

In this paper, we propose the least-squares method for computing the positive solution of a $m\times n$ fully fuzzy linear system (FFLS) of equations, where $m > n$, based on Kaffman's arithmetic operations on fuzzy numbers that introduced in [18]. First, we consider all elements of ...

##### 5. Expansion methods for solving integral equations with multiple time lags using Bernstein polynomial of the second kind

*Volume 03, Issue 01 , Winter 2014, Pages 35-45*

#####
**Abstract **

In this paper, the Bernstein polynomials are used to approximate the solutions of linear integral equations with multiple time lags (IEMTL) through expansion methods (collocation method, partition method, Galerkin method). The method is discussed in detail and illustrated by solving some numerical ...

##### 6. Cubic spline Numerov type approach for solution of Helmholtz equation

*Volume 03, Issue 01 , Winter 2014, Pages 47-54*

#####
**Abstract **

We have developed a three level implicit method for solution of the Helmholtz equation. Using the cubic spline in space and finite difference in time directions. The approach has been modied to drive Numerov type nite difference method. The method yield the tri-diagonal linear system of ...
