##### 1. Normalized laplacian spectrum of two new types of join graphs

*Volume 06, Issue 01 , Winter 2017, Pages 1-9*

#####
**Abstract **

Let $G$ be a graph without an isolated vertex, the normalized Laplacian matrix $\tilde{\mathcal{L}}(G)$ is defined as $\tilde{\mathcal{L}}(G)=\mathcal{D}^{-\frac{1}{2}}\mathcal{L}(G)\mathcal{D}^{-\frac{1}{2}}$, where $\mathcal{D}$ is a diagonal matrix ...

##### 2. The method of radial basis functions for the solution of nonlinear Fredholm integral equations system.

*Volume 06, Issue 01 , Winter 2017, Pages 11-28*

#####
**Abstract **

In this paper, An effective and simple numerical method is proposed for solving systems of integral equations using radial basis functions (RBFs). We present an algorithm based on interpolation by radial basis functions including multiquadratics (MQs), using Legendre-Gauss-Lobatto nodes and weights. ...

##### 3. Unique common coupled fixed point theorem for four maps in $S_b$-metric spaces

*Volume 06, Issue 01 , Winter 2017, Pages 29-43*

#####
**Abstract **

In this paper we prove a unique common coupled fixed point theorem for two pairs of $w$-compatible mappings in $S_b$-metric spaces satisfying a contrctive type condition. We furnish an example to support our main theorem. We also give a corollary for Junck type maps.

##### 5. Characterization of $\delta$-double derivations on rings and algebras

*Volume 06, Issue 01 , Winter 2017, Pages 55-65*

#####
**Abstract **

The main purpose of this article is to offer some characterizations of $\delta$-double derivations on rings and algebras. To reach this goal, we prove the following theorem:Let $n > 1$ be an integer and let $\mathcal{R}$ be an $n!$-torsion free ring with the identity element $1$. Suppose ...
