  • A numerical solution of mixed Volterra Fredholm integral equations of Urysohn type on non-rectangular regions using meshless methods 

    Nili Ahmadabadi, M.؛ Laeli Dastjerdi, H. (Central Tehran Branch, Islamic Azad University, 2015-12-01)
    In this paper, we propose a new numerical method for solution of Urysohn two dimensional mixed Volterra-Fredholm integral equations of the second kind on a non-rectangular domain. The method approximates the solution by ...

  • Some results on higher numerical ranges and radii of quaternion matrices 

    Aghamollaei, Gh.؛ Haj Aboutalebi, N. (Central Tehran Branch, Islamic Azad University, 2015-12-01)
    ‎Let $n$ and $k$ be two positive integers‎, ‎$kleq n$ and $A$ be an $n$-square quaternion matrix‎. ‎In this paper‎, ‎some results on the $k-$numerical range of $A$ are investigated‎. ‎Moreover‎, ‎the notions of $k$-numerical ...

  • Quotient Arens regularity of $L^1(G)$ 

    Zivari-Kazempour, A. (Central Tehran Branch, Islamic Azad University, 2015-12-01)
    Let $mathcal{A}$ be a Banach algebra with BAI and $E$ be an introverted subspace of $mathcal{A}^prime$. In this paper we study the quotient Arens regularity of $mathcal{A}$ with respect to $E$ and prove that the group ...

  • Generalized superconnectedness 

    Bouassida, E.؛ Ghanmi, B.؛ Messaoud, R.؛ Missaoui, A. (Central Tehran Branch, Islamic Azad University, 2015-12-01)
    A. Csaszar introduced and extensively studied the notion of generalized open sets. Following Csazar, we introduce a new notion superconnected. The main purpose of this paper is to study generalized superconnected spaces. ...

  • A new Approximation to the solution of the linear matrix equation AXB = C 

    Sadeghi, A. (Central Tehran Branch, Islamic Azad University, 2015-12-01)
    It is well-known that the matrix equations play a significant role in several applications in science and engineering. There are various approaches either direct methods or iterative methods to evaluate the solution of ...

  • Duals and approximate duals of g-frames in Hilbert spaces 

    Mirzaee Azandaryani, M.؛ Khosravi, A. (Central Tehran Branch, Islamic Azad University, 2015-12-01)
    In this paper we get some results and applications for duals and approximate duals of g-frames in Hilbert spaces. In particular, we consider the stability of duals and approximate duals under bounded operators and we study ...

  • Classical Wavelet Transforms over Finite Fields 

    Ghaani Farashahi, A. (Central Tehran Branch, Islamic Azad University, 2015-12-01)
    This article introduces a systematic study for computational aspects of classical wavelet transforms over finite fields using tools from computational harmonic analysis and also theoretical linear algebra. We present a ...
