  • On the Degree of Approximation of Functions Belonging to the Lipschitz Class by (E, q)(C, α, β) Means 

    Krasniqi, Xhevat Z. (Department of Pure Mathematics, Ferdowsi University of Mashhad (in cooperation with the Center of Excellence in Analysis on Algebraic Structures and Tusi Mathematical Research Group), 2015-08-01)
    In this paper two generalized theorems on the degree of approximation of conjugate functions belonging to the Lipschitz classes of the type $text{Lip}alpha $, $0

  • Statistical Ergodic Theorems for Markov Semigroups in Spaces with Mixed Norm 

    Ganiev, Inomjon؛ Sadaddinova, Sanobar؛ Ganiev, Umarjon (Department of Pure Mathematics, Ferdowsi University of Mashhad (in cooperation with the Center of Excellence in Analysis on Algebraic Structures and Tusi Mathematical Research Group), 2015-08-01)
    This paper describes the semigroups generated by the Markov processes in spaces with mixed norm and proves analogues of statistical ergodic theorems for such semigroups.

  • Exponential Stability and Instability in Multiple Delays Difference Equations 

    Almutairy, S.؛ Alshammari, M.؛ Raffoul, Y. (Department of Pure Mathematics, Ferdowsi University of Mashhad (in cooperation with the Center of Excellence in Analysis on Algebraic Structures and Tusi Mathematical Research Group), 2015-08-01)
    We use Lyapunov functionals and obtain sufficient conditions that guarantee exponential stability of the zero solution of the difference equation with multiple delays begin{equation*} x(t+1) = a(t)x(t)+sum^{k}_{j=1}b_j(t)x(t-h_j). ...

  • Toeplitz and Hankel Operators on a Vector-valued Bergman Space 

    Das, Namita (Department of Pure Mathematics, Ferdowsi University of Mashhad (in cooperation with the Center of Excellence in Analysis on Algebraic Structures and Tusi Mathematical Research Group), 2015-08-01)
    In this paper, we derive certain algebraic properties of Toeplitz and Hankel operators defined on the vector-valued Bergman spaces $L_a^{2, mathbb{C}^n}(mathbb{D})$, where $mathbb{D}$ is the open unit disk in $mathbb{C}$ ...

  • Lipschitz Tensor Product 

    Cabrera-Padilia, M.G.؛ Chavez-Dominguez, J.A.؛ Jimenez-Vargas, A.؛ Viliegas-Vallecillos, M. (Department of Pure Mathematics, Ferdowsi University of Mashhad (in cooperation with the Center of Excellence in Analysis on Algebraic Structures and Tusi Mathematical Research Group), 2015-08-01)
    Inspired by ideas of R. Schatten in his celebrated monograph [23] on a theory of cross-spaces, we introduce the notion of a Lipschitz tensor product $Xboxtimes E$ of a pointed metric space $X$ and a Banach space $E$ as a ...
