##### 176. On the nonnegative inverse eigenvalue problem of traditional matrices

A. M. Nazari; S. Kamali Maher

Volume 02, Issue 03 , Summer 2013, , Pages 167-174

##### Abstract
In this paper, at first for a given set of real or complex numbers $\sigma$ with nonnegative summation, we introduce some special conditions that with them there is no nonnegative tridiagonal matrix in which $\sigma$ is its spectrum. In continue we present some conditions for existence such nonnegative ...  Read More

##### 177. Module amenability and module biprojectivity of θ-Lau product of Banach algebras

D. Ebrahimi Bagha; H. Azaraien

Volume 03, Issue 03 , Summer 2014, , Pages 185-196

##### Abstract
In this paper we study the relation between module amenability of $\theta$-Lau product $A×_\theta B$ and that of Banach algebras $A, B$. We also discuss module biprojectivity of $A×\theta B$. As a consequent we will see that for an inverse semigroup $S$, $l^1(S)×_\theta l^1(S)$ is module ...  Read More

Volume 08, Issue 03 , Summer 2019, , Pages 203-209

##### Abstract
‎Let $S$ be an inverse semigroup with the set of idempotents $E$‎. We prove that the semigroup algebra $\ell^{1}(S)$ is always‎ ‎$2n$-weakly module amenable as an $\ell^{1}(E)$-module‎, ‎for any‎ ‎$n\in \mathbb{N}$‎, ‎where $E$ acts on $S$ trivially ...  Read More

Volume 04, Issue 03 , Summer 2015, , Pages 217-228

##### Abstract
In this work, we conduct a comparative study among the combine Laplace transform and modi ed Adomian decomposition method (LMADM) and two traditional methods for an analytic and approximate treatment of special type of nonlinear Volterra integro-differential equations of the second kind. The nonlinear ...  Read More

##### 181. 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

##### 182. Suzuki-Berinde type fixed-point and fixed-circle results on $S$-metric spaces

N. TAŞ

Volume 07, Issue 03 , Summer 2018, , Pages 233-244

##### Abstract
In this paper, the notions of a Suzuki-Berinde type $F_{S}$-contraction and a Suzuki-Berinde type $F_{C}^{S}$-contraction are introduced on a $S$-metric space. Using these new notions, a fixed-point theorem is proved on a complete $S$-metric space and a fixed-circle theorem is established on ...  Read More

##### 186. Dynamical distance as a semi-metric on nuclear con guration space

M. Rahimi

Volume 05, Issue 04 , Autumn 2016, , Pages 279-287

##### Abstract
In this paper, we introduce the concept of dynamical distance on a nuclear con guration space. We partition the nuclear conguration space into disjoint classes. This classifi cation coincides with the classical partitioning of molecular systems via the concept of conjugacy of dynamical systems. ...  Read More
