  • Existence of an $L^p$-solution for two dimensional integral equations of the Hammerstein type 

    Hosseini, S. A.؛ Shahmorad, S.؛ Tari, A. (Springer and the Iranian Mathematical Society (IMS), 2014-08-01)
    In this paper‎, ‎existence of an $L^p$-solution for 2DIEs (Two‎ ‎Dimensional Integral Equations) of the Hammerstein type is‎ ‎discussed‎. ‎The main tools in this discussion are Schaefer's and‎ ‎Schauder's ...

  • Frobenius kernel and Wedderburn's little theorem 

    Amiri, M.؛ Ariannejad, M. (Springer and the Iranian Mathematical Society (IMS), 2014-08-01)
    We give a new proof of the well known Wedderburn's little theorem (1905) that a finite‎ ‎division ring is commutative‎. ‎We apply the concept of Frobenius kernel in Frobenius representation theorem in finite group‎ ...

  • Higher order close-to-convex functions associated with Attiya-Srivastava operator 

    Hussain, S.؛ Arif, M.؛ Nawaz Malik, S‎. ‎ (Springer and the Iranian Mathematical Society (IMS), 2014-08-01)
    In this paper‎, ‎we introduce a new class$T_{k}^{s,a}[A,B,alpha‎ ,‎beta ]$ of analytic functions by using a‎ ‎newly defined convolution operator‎. ‎This class contains many known classes of‎ ‎analytic and univalent ...

  • Lexicographical ordering by spectral moments of trees with a given bipartition 

    L i, S.؛ Zhang, J. (Springer and the Iranian Mathematical Society (IMS), 2014-08-01)
    Lexicographic ordering by spectral moments ($S$-order) among all trees is discussed in this‎ ‎paper‎. ‎For two given positive integers $p$ and $q$ with $pleqslant q$‎, ‎we denote $mathscr{T}_n^{p‎, ‎q}={T‎: ‎T$ is a tree ...

  • A modified Mann iterative scheme for a sequence of‎ ‎nonexpansive mappings and a monotone mapping with applications 

    ‎Bagherboum, M.؛ Razani, A. (Springer and the Iranian Mathematical Society (IMS), 2014-08-01)
    ‎In a real Hilbert space‎, ‎an iterative scheme is considered to‎ ‎obtain strong convergence which is an essential tool to find a‎ ‎common fixed point for a countable family of nonexpansive mappings‎ ‎and ...

  • On quasi-Einstein Finsler spaces‎ 

    Bidabad, B.؛ Yarahmadi, M. (Springer and the Iranian Mathematical Society (IMS), 2014-08-01)
    ‎The notion of quasi-Einstein metric in physics is equivalent to the notion of Ricci soliton in Riemannian spaces‎. ‎Quasi-Einstein metrics serve also as solution to the Ricci flow equation‎. ‎Here‎, ‎the Riemannian metric ...

  • On the sum of Pell and Jacobsthal numbers by matrix method 

    Akbulak, M.؛ Öteleș, A. (Springer and the Iranian Mathematical Society (IMS), 2014-08-01)
    In this paper‎, ‎we define two $n$-square upper Hessenberg matrices one of which corresponds to the adjacency matrix of a directed pseudo graph‎. ‎We investigate relations between permanents and determinants of these upper ...

  • Quintasymptotic sequences over an ideal and quintasymptotic cograde 

    Jahandoust, S.؛ Naghipour, R. (Springer and the Iranian Mathematical Society (IMS), 2014-08-01)
    ‎Let $I$ denote an ideal of a Noetherian ring $R$‎. ‎The purpose of‎ ‎this article is to introduce the concepts of quintasymptotic‎ ‎sequences over $I$ and quintasymptotic cograde of $I$‎, ‎and to show that they play a ...

  • Reversibility of a module with respect to the bifunctors Hom and‎ ‎Rej 

    Tolooei, Y.؛ Vedadi, M. R. (Springer and the Iranian Mathematical Society (IMS), 2014-08-01)
    Let $M_R$ be a non-zero‎ ‎module and ${mathcal F}‎: ‎sigma[M_R]times sigma[M_R]‎ ‎rightarrow$ Mod-$Bbb{Z}$ a bifunctor‎. ‎The‎ ‎$mathcal{F}$-reversibility of $M$ is defined by ${mathcal‎ ‎F}(X,Y)=0 Rightarrow {mathcal ...

  • Strong convergence of a general implicit algorithm for variational inequality problems and equilibrium problems and a continuous representation of nonexpansive mappings 

    Lashkarizadeh Bami, M.؛ Soori, E. (Springer and the Iranian Mathematical Society (IMS), 2014-08-01)
    We introduce a general implicit algorithm for finding a common element of‎ ‎the set of solutions of systems of equilibrium problems and the set of common fixed points‎ ‎of a sequence of nonexpansive mappings ...

  • Strong convergence of modified noor iteration in CAT(0) spaces 

    Cuntavepanit, A. (Springer and the Iranian Mathematical Society (IMS), 2014-08-01)
    We prove a strong convergence theorem for the modified Noor iterations‎ ‎in the framework of CAT(0) spaces‎. ‎Our results extend and improve the corresponding results of‎ ‎X‎. ‎Qin‎, ‎Y‎. ‎Su and M‎. ‎Shang‎, ‎T‎. ‎H‎. ...

  • A strong convergence theorem for solutions of zero point problems and fixed point problems 

    Cho, S. Y.؛ Qin, X.؛ Wang, L. (Springer and the Iranian Mathematical Society (IMS), 2014-08-01)
