  • T-Rough Sets Based on the Lattices 

    Hosseini, S.B.؛ Hosseinpour, E. (University of Mazandaranدانشگاه مازندران, 2013-05-01)
    The aim of this paper is to introduce and study set- valued homomorphism on lattices and T-rough lattice with respect to a sublattice. This paper deals with T-rough set approach on the lattice theory. The ...

  • Solving a System of Linear Equations by Homotopy Analysis Method 

    Bayat, M.؛ Khatami, Z. (University of Mazandaranدانشگاه مازندران, 2013-05-01)
    ‎In this paper‎, ‎an efficient algorithm for solving a system of linear‎ ‎equations based on the homotopy analysis method is presented‎. ‎The‎ ‎proposed method is compared with the classical Jacobi iterative‎ ...

  • On the existence of nonnegative solutions for a class of fractional boundary value problems 

    Babakhani, A. (University of Mazandaranدانشگاه مازندران, 2013-05-01)
    ‎In this paper‎, ‎we provide sufficient conditions for the existence of nonnegative solutions of a boundary value problem for a fractional order differential equation‎. ‎By applying Kranoselskii`s fixed--point theorem in ...

  • Fixed point approach to the Hyers-Ulam-Rassias approximation‎ ‎of homomorphisms and derivations on Non-Archimedean random Lie $C^*$-algebras 

    Azadi Kenary, H.؛ Toorani, A.؛ Heidarzadegan, A. (University of Mazandaranدانشگاه مازندران, 2013-05-01)
    ‎In this paper‎, ‎using fixed point method‎, ‎we prove the generalized Hyers-Ulam stability of‎ ‎random homomorphisms in random $C^*$-algebras and random Lie $C^*$-algebras‎ ‎and of derivations on Non-Archimedean ...

  • $C_4$-free zero-divisor graphs 

    Jafari, S. H. (University of Mazandaranدانشگاه مازندران, 2013-05-01)
    ‎In this paper we give a characterization for all commutative‎ ‎rings with $1$ whose zero-divisor graphs are $C_4$-free.‎

  • INEXTENSIBLE FLOWS OF CURVES IN LIE GROUPS 

    Yildiz, G.؛ Okuyucu, O. Z. (University of Mazandaranدانشگاه مازندران, 2013-05-01)
    In this paper, we study inextensible ows in three dimensional Lie groups with a bi-invariant metric. The necessary and su cient conditions for inextensible curve ow are expressed as a partial dierential ...
