  • On a sequence related to the coprime integers 

    Hassani, Mehdi (University of Maragheh, 2014-12-01)
    The asymptotic behaviour of the sequence with general term $P_n=(varphi(1)+varphi(2)+cdots+varphi(n))/(1+2+cdots+n)$, is studied which appears in the studying of coprime integers, and an explicit bound for the difference ...

  • Simulation study on copulas 

    Tekin, Sinem Tuğba Şahin؛ Najjari, Vadoud؛ Örkcü, H. Hasan (University of Maragheh, 2014-12-01)
    There are several theorical results about order statistics and copulas in the literature that have  been mentioned also by Nelsen cite{p20}. The present study after reviewing some of these results, relies on  simulation ...

  • Commutative curvature operators over four-dimensional generalized symmetric spaces 

    Haji-Badali, Ali؛ Dehghan, Masoud؛ Nourmohammadi, Fereshteh (University of Maragheh, 2014-12-01)
    Commutative properties of four-dimensional generalized symmetric pseudo-Riemannian manifolds were considered. Specially, in this paper, we studied Skew-Tsankov and Jacobi-Tsankov conditions in 4-dimensional pseudo-Riemannian ...

  • Nonstandard finite difference schemes for differential equations 

    Mehdizadeh Khalsaraei, Mohammad؛ Khodadosti, Fayyaz (University of Maragheh, 2014-12-01)
    In this paper, the reorganization of the denominator of the discrete derivative and nonlocal approximation of nonlinear terms are used in the design of nonstandard finite difference schemes (NSFDs). Numerical examples ...

  • A unified theoretical harmonic analysis approach to the cyclic wavelet transform (CWT) for periodic signals of prime dimensions 

    Ghaani Farashahi, Arash؛ Mohammad-Pour, Mozhgan (University of Maragheh, 2014-12-01)
    The article introduces cyclic dilation groups and finite affine groups for prime integers, and  as an application of this theory it presents a unified group theoretical approach for the  cyclic wavelet transform (CWT) of ...
