  • A representation for some groups, a geometric approach 

    Parsian, A. (Central Tehran Branch, Islamic Azad University, 2018-06-01)
    ‎In the present paper‎, ‎we are going to use geometric and topological concepts‎, ‎entities and properties of the‎ ‎integral curves of linear vector fields‎, ‎and the theory of differential equations‎, ‎to establish a ...

  • New three-step iteration process and fixed point approximation in Banach spaces 

    Ullah, K.؛ Arshad, M. (Central Tehran Branch, Islamic Azad University, 2018-06-01)
    ‎In this paper we propose a new iteration process‎, ‎called the $K^{ast }$ iteration process‎, ‎for approximation of fixed‎ ‎points‎. ‎We show that our iteration process is faster than the existing well-known iteration ...

  • Stability and hyperstability of orthogonally ring $*$-$n$-derivations and orthogonally ring $*$-$n$-homomorphisms on $C^*$-algebras 

    Gholami, R.؛ Askari, Gh.؛ Eshaghi Gordji, M. (Central Tehran Branch, Islamic Azad University, 2018-06-01)
    In this paper, we investigate the generalized Hyers-Ulam-Rassias and the Isac and Rassias-type stability of the conditional of orthogonally ring $*$-$n$-derivation and orthogonally ring $*$-$n$-homomorphism on $C^*$-algebras. ...

  • On the powers of fuzzy neutrosophic soft matrices 

    Kavitha, M.؛ Murugadas, P.؛ Sriram, S. (Central Tehran Branch, Islamic Azad University, 2018-06-01)
    In this paper, ‎The powers of fuzzy neutrosophic soft square matrices (FNSSMs) under the operations $oplus(=max)$ and $otimes(=min)$ are studied‎. ‎We show that the powers of a given FNSM stabilize if and only if its orbits ...

  • On Laplacian energy of non-commuting graphs of finite groups 

    Dutta, P.؛ Nath, R. K. (Central Tehran Branch, Islamic Azad University, 2018-06-01)
    ‎Let $G$ be a finite non-abelian group with center $Z(G)$‎. ‎The non-commuting graph of $G$ is a simple undirected graph whose vertex set is $Gsetminus Z(G)$ and two vertices $x$ and $y$ are adjacent if and only if $xy ne ...

  • A note on the new basis in the mod 2 Steenrod algebra 

    Vergili, T.؛ Karaca, I. (Central Tehran Branch, Islamic Azad University, 2018-06-01)
    ‎The Mod $2$ Steenrod algebra is a Hopf algebra that consists of the primary cohomology operations‎, ‎denoted by $Sq^n$‎, ‎between the cohomology groups with $mathbb{Z}_2$ coefficients of any topological space‎. ‎Regarding ...

  • Numerical solution of a type of weakly singular nonlinear Volterra integral equation by Tau Method 

    Laeli Dastjerdi, H.؛ Nili Ahmadabadi, M. (Central Tehran Branch, Islamic Azad University, 2018-06-01)
    ‎In this paper‎, ‎a matrix based method is considered for the solution of a class of nonlinear Volterra integral equations with a kernel of the general form $s^{beta}(t-s)^{-alpha}G(y(s))$ based on the Tau method‎. ‎In ...
