  • Solution and stability analysis of coupled nonlinear Schrodinger equations 

    شاه منصوری, م.؛ فرخی, ّب. (Islamic Azad University of Arak, 2011-01-01)
    We consider a new type of integrable coupled nonlinear Schrodinger (CNLS)equations proposed by our self [submitted to Phys. Plasmas (2011)]. The explicitform of soliton solutions are derived using the Hirota's ...

  • Best approximation by closed unit balls 

    کمالی, ه.ر.؛ مظاهری, ه؛ خاده زاده, ه.ر.؛ اردکانی, ه (Islamic Azad University of Arak, 2011-01-01)
    We obtain a su cint and nesessery theoreoms simple for compactness andweakly compactness of the best approximate sets by closed unit balls. Also weconsider relations Kadec-Klee property and shur property with ...

  • A Legendre-spectral scheme for solution of nonlinear system of Volterra-Fredholm integral equations 

    هوشنگیان, ل.؛ میرزایی, د. (Islamic Azad University of Arak, 2011-01-01)
    This paper gives an e cient numerical method for solving the nonlinear systemof Volterra-Fredholm integral equations. A Legendre-spectral method based onthe Legendre integration Gauss points and Lagrange ...

  • Some fi xed points for J-type multi-valued maps in CAT(0) spaces 

    حسینی غنچه, سید جلال؛ صلاحی فرد, ه. (Islamic Azad University of Arak, 2011-01-01)
    In this paper, we prove the existence of fi xed point for J-type multi-valuedmap T in CAT(0) spaces and also we prove the strong convergence theoremsfor Ishikawa iteration scheme without using the xed point ...
