BodaghiDepartment of Mathematics, Garmsar Branch, Islamic Azad University, Garmsar, IranB. ShojaeeDepartment of Mathematics, Karaj Branch, Islamic Azad University, Karaj, IranJournal Article20150412Let $nin mathbb{N}$. An additive map $h:Ato B$ between algebras $A$ and $B$ is called $n$-Jordan homomorphism if $h(a^n)=(h(a))^n$ for all $ain A$. We show that every $n$-Jordan homomorphism between commutative Banach algebras is a $n$-ring homomorphism when $n < 8$. For these cases, every involutive $n$-Jordan homomorphism between commutative C-algebras is norm continuous.Central Tehran Branch, Islamic Azad UniversityJournal of Linear and Topological Algebra (JLTA)2252-0201010120120301Some notes on L-projections on Fourier-Stieltjes algebras913510060ENM.

Code 14168-94351, IranJournal Article20120101Let $R$ be a prime ring with extended centroid $C$, $H$ a generalized derivation of $R$ and $ngeq 1$ a fixed integer. In this paper we study the situations: (1) If $(H(xy))^n =(H(x))^n(H(y))^n$ for all $x,yin R$; (2) obtain some related result in case $R$ is a noncommutative Banach algebra and $H$ is continuous or spectrally bounded.Central Tehran Branch, Islamic Azad UniversityJournal of Linear and Topological Algebra (JLTA)2252-0201010120120301Solving the liner quadratic differential equations with constant coefficients using Taylor series with step size h2125510062ENM. KarimianDepartment of Mathematics, Islamic Azad University, Abdanan Branch, Ilam, IranJournal Article20120101In this study we produced a new method for solving regular differential equations with step size h and Taylor series. This method analyzes a regular differential equation with initial values and step size h. this types of equations include quadratic and cubic homogenous equations with constant coeffcients and cubic and second-level equations.Central Tehran Branch, Islamic Azad UniversityJournal of Linear and Topological Algebra (JLTA)2252-0201010120120301OD-characterization of almost simple groups related to U3(11)2732510063ENP.

DarafshehSchool of mathematics, College of Science, University of Tehran, Tehran, IranJournal Article20120101Let $L := U_3(11)$. In this article, we classify groups with the same order and degree pattern as an almost simple group related to $L$. In fact, we prove that $L$, $L:2$ and $L:3$ are OD-characterizable, and $L:S_3$ is $5$-fold OD-characterizable.Central Tehran Branch, Islamic Azad UniversityJournal of Linear and Topological Algebra (JLTA)2252-0201010120120301New fixed and periodic point results on cone metric spaces3340510064ENGh.
