  • Common fixed point of four maps in $S_b$-Metric spaces 

    Radenovic, S.؛ Sedghi, Sh.؛ Gholidahneh, A.؛ Dosenovic, T.؛ Esfahani, J. (Central Tehran Branch, Islamic Azad University, 2016-05-01)
    In this paper is introduced a new type of generalization of metric spaces called $S_b$ metric space. For this new kind of spaces it has been proved a common fixed point theorem for four mappings which satisfy generalized ...

  • On $m^{th}$-autocommutator subgroup of finite abelian groups 

    Gholamian, A.؛ Nasrabadi, M. M. (Central Tehran Branch, Islamic Azad University, 2016-05-01)
    Let $G$ be a group and $Aut(G)$ be the group of automorphisms of‎ ‎$G$‎. ‎For any natural‎ number $m$‎, ‎the $m^{th}$-autocommutator subgroup of $G$ is defined‎ ‎as‎: ‎$$K_{m} (G)=langle[g,alpha_{1},ldots,alpha_{m}] |gin ...

  • Asymptotic aspect of quadratic functional equations and super stability of higher derivations in multi-fuzzy normed spaces 

    khanehgir, M.؛ Hasanvand, F. (Central Tehran Branch, Islamic Azad University, 2016-05-01)
    In this paper, we introduce the notion of multi-fuzzy normed spaces and establish an asymptotic behavior of the quadratic functional equations in the setup of such spaces. We then investigate the superstability of strongly ...

  • Bipolar general fuzzy automata 

    Horry, M. (Central Tehran Branch, Islamic Azad University, 2016-05-01)
    In this paper, we define the notion of a bipolar general fuzzy automaton, then we construct some closure operators on the set of states of a bipolar general fuzzy automaton. Also, we construct some topologies on the set ...

  • On categories of merotopic, nearness, and filter algebras 

    Gompa, V. (Central Tehran Branch, Islamic Azad University, 2016-05-01)
    We study algebraic properties of categories of Merotopic, Nearness, and Filter Algebras. We show that the category of filter torsion free abelian groups is an epireflective subcategory of the category of filter abelian ...

  • Random fixed point theorems with an application to a random nonlinear integral equation 

    Rashwan, R. A.؛ Hammad, H. A. (Central Tehran Branch, Islamic Azad University, 2016-05-01)
    In this paper, stochastic generalizations of some fixed point for operators satisfying random contractively generalized hybrid and some other contractive condition have been proved. We discuss also the existence of a ...
