##### 1. Characterization of $(\delta, \varepsilon)$-double derivation on rings and algebras

*Volume 06, Issue 03 , Summer 2017, Pages 191-198*

#####
**Abstract **

This paper is an attempt to prove the following result:Let $n>1$ be an integer and let $\mathcal{R}$ be a $n!$-torsion-free ring with the identity element. Suppose that $d, \delta, \varepsilon$ are additive mappings satisfying\begin{equation}d(x^n) = \sum^{n}_{j=1}x^{n-j}d(x)x^{j-1}+\sum^{n-1}_{j=1}\sum^{j}_{i=1}x^{n-1-j}\Big(\delta(x)x^{j-i}\varepsilon(x)+\varepsilon(x)x^{j-i}\delta(x)\Big)x^{i-1}\quad\end{equation}for ...

##### 2. Fuzzy almost generalized $e$-continuous mappings

*Volume 06, Issue 03 , Summer 2017, Pages 199-206*

#####
**Abstract **

In this paper, we introduce and characterize the concept of fuzzy almost generalized $e$-continuous mappings. Several interesting properties of these mappings are also given. Examples and counter examples are also given to illustrate the concepts introduced in the paper. We also introduce the concept ...

##### 3. Spectral triples of weighted groups

*Volume 06, Issue 03 , Summer 2017, Pages 207-216*

#####
**Abstract **

We study spectral triples on (weighted) groups and consider functors between the categories of weighted groups and spectral triples. We study the properties of weights and the corresponding functor for spectral triples coming from discrete weighted groups.

##### 4. On some Frobenius groups with the same prime graph as the almost simple group ${ {\bf PGL(2,49)}}$

*Volume 06, Issue 03 , Summer 2017, Pages 217-221*

#####
**Abstract **

The prime graph of a finite group $G$ is denoted by $\Gamma(G)$ whose vertex set is $\pi(G)$ and two distinct primes $p$ and $q$ are adjacent in $\Gamma(G)$, whenever $G$ contains an element with order $pq$. We say that $G$ is unrecognizable by prime graph if there is a finite group $H$ with $\Gamma(H)=\Gamma(G)$, ...

##### 5. Interval valued fuzzy weak bi-ideals of $\Gamma$-near-rings

*Volume 06, Issue 03 , Summer 2017, Pages 223-236*

#####
**Abstract **

In this paper, we introduce the concept of interval valued fuzzy weak bi-ideals of $\Gamma$-near-rings, which is a generalized concept of fuzzy weak bi-ideals of $\Gamma$- near-rings. We also characterize some properties and examples of interval valued fuzzy weak bi-ideals of $\Gamma$-near-rings.

##### 6. Numerical solution of a system of fuzzy polynomial equations by modified Adomian decomposition method

*Volume 06, Issue 03 , Summer 2017, Pages 237-250*

#####
**Abstract **

In this paper, we present some efficient numerical algorithm for solving system of fuzzy polynomial equations based on Newton's method. The modified Adomian decomposition method is applied to construct the numerical algorithms. Some numerical illustrations are given to show the efficiency ...
