  • Existence results for equilibrium problems under strong sign property 

    Jafari, Somaye؛ Farajzadeh, Ali (Semnan University, 2017-04-01)
    This paper concerns equilibrium problems in real metric linear spaces. Considering a modified notion of  upper sign property for bifunctions, we obtain the relationship between the solution sets of the local Minty equilibrium ...

  • Hermite-Hadamard inequalities for $mathbb{B}$-convex and $mathbb{B}^{-1}$-convex functions 

    Yesilce, Ilknur؛ Adilov, Gabil (Semnan University, 2017-04-01)
    Hermite-Hadamard inequality is one of the fundamental applications of convex functions in Theory of Inequality. In this paper, Hermite-Hadamard inequalities for $mathbb{B}$-convex and $mathbb{B}^{-1}$-convex functions are proven.

  • A note on the Young type inequalities 

    Nasiri, Leila؛ Shakoori, Mahmood؛ Liao, Wenshi (Semnan University, 2017-04-01)
    In this   paper,  we   present  some  refinements  of the   famous Young  type  inequality.   As  application  of   our   result, we  obtain  some  matrix inequalities   for   the  Hilbert-Schmidt norm  and   the  trace   ...

  • On new faster fixed point iterative schemes for contraction operators and comparison of their rate of convergence in convex metric spaces 

    Alecsa, Cristian (Semnan University, 2017-04-01)
    In this paper we present new iterative algorithms in convex metric spaces. We show that these iterative schemes are convergent to the fixed point of a single-valued contraction operator. Then we make the comparison of their ...

  • On the metric triangle inequality 

    Mihai Bica, Alexandre (Semnan University, 2017-04-01)
    A non-contradictible axiomatic theory is constructed under the local reversibility of the metric triangle inequality. The obtained notion includes the metric spaces as particular cases and the generated metric topology is ...

  • Periodic boundary value problems for controlled nonlinear impulsive evolution equations on Banach spaces 

    Melliani, Said؛ Chadli, Lalla Saadia؛ El Allaoui, Abdelati (Semnan University, 2017-04-01)
    This paper deals with the Periodic boundary value problems for Controlled nonlinear impulsive evolution equations. By using the theory of semigroup and fixed point methods, some conditions ensuring the existence and ...

  • Quadratic $alpha$-functional equations 

    Park, Choonkil؛ Kim, Sang Og (Semnan University, 2017-04-01)
    In this paper, we solve the quadratic $alpha$ -functional equations $2f(x) + 2f(y) = f(x + y) + alpha^{-2}f( alpha(x-y)); (0.1)$ where $alpha$ is a fixed non-Archimedean number with $alpha^{-2}neq 3$. Using the fixed ...

  • Similarity measurement for describe user images in social media 

    Tavakoli Targhi, Alireza (Semnan University, 2017-04-01)
    Online social networks like Instagram are places for communication. Also, these media produce rich metadata which are useful for further analysis in many fields including health and cognitive science. Many researchers are ...

  • Some properties of analytic functions related with bounded positive real part 

    Kargar, Rahim؛ Ebadian, Ali؛ Sokol, Janusz (Semnan University, 2017-04-01)
    In this paper, we define new subclass of analytic functions related with bounded positive real part, and coefficients estimates, duality and neighborhood are considered.

  • The structure of ideals, point derivations, amenability and weak amenability of extended Lipschitz algebras 

    Mayghani, Maliheh؛ Alimohammadi, Davood (Semnan University, 2017-04-01)
    Let $(X,d)$ be a compactmetric space and let $K$ be a nonempty compact subset of $X$. Let $alpha in (0, 1]$ and let ${rm Lip}(X,K,d^ alpha)$ denote the Banach algebra of all  continuous complex-valued functions $f$ ...

  • Uncertainty in linear fractional transportation problem 

    Safi, Mohammad Reza؛ Ghasemi, Seyyed Mojtaba (Semnan University, 2017-04-01)
    In this paper, we study the linear fractional transportation problem with uncertain arameters. After recalling some definitions, concepts and theorems in uncertainty theory we present three approaches for solving this ...
