  • $(-1)$-Weak Amenability of Second Dual of Real Banach Algebras 

    Alihoseini, Hamidreza؛ Alimohammadi, Davood (University of Maragheh, 2018-11-01)
    Let $ (A,| cdot |) $ be a real Banach algebra, a complex algebra $ A_mathbb{C} $ be a complexification of $ A $ and $ | | cdot | | $ be an algebra norm on  $ A_mathbb{C}  $  satisfying a simple condition together with the ...

  • A Certain Class of Character Module Homomorphisms on Normed Algebras 

    Khoddami, Ali Reza (University of Maragheh, 2018-11-01)
    For two normed algebras $A$ and $B$ with the character space   $bigtriangleup(B)neq emptyset$  and a left $B-$module $X,$  a certain class of bounded linear maps from $A$ into $X$ is introduced. We set $CMH_B(A, X)$  as ...

  • Inequality Problems of Equilibrium Problems with Application 

    Eleiwis Hashoosh, Ayed؛ Alimohammady, Mohsen؛ Mohsen Buite, Haiffa (University of Maragheh, 2018-11-01)
    This paper aims at establishing the existence of results for a nonstandard equilibrium problems $(EP_{N})$. The solutions of this inequality are discussed in a subset $K$ (either bounded or unbounded) of a Banach spaces ...

  • $L^p$-Conjecture on Hypergroups 

    Tabatabaie, Seyyed Mohammad؛ Haghighifar, Faranak (University of Maragheh, 2018-11-01)
    In this paper, we study $L^p$-conjecture on locally compact hypergroups and by some technical proofs we give some sufficient and necessary conditions  for a weighted Lebesgue space  $L^p(K,w)$ to be a convolution Banach ...

  • A New Approach to Nonstandard Analysis 

    Abdeljalil, Saghe (University of Maragheh, 2018-11-01)
    In this paper, we propose a new approach to nonstandard analysis without using the ultrafilters. This method is very simple in practice. Moreover, we construct explicitly the total order relation in the new field of the ...

  • The Norm Estimates of Pre-Schwarzian Derivatives of Spirallike Functions and Uniformly Convex $alpha$-spirallike Functions 

    Orouji, Zahra؛ Aghalary, Rasul (University of Maragheh, 2018-11-01)
    For a constant $alphain left(-frac{pi}{2},frac{pi}{2}right)$,  we definea  subclass of the spirallike functions, $SP_{p}(alpha)$, the setof all functions $fin mathcal{A}$[releft{e^{-ialpha}frac{zf ...

  • Numerical Reckoning Fixed Points in $CAT(0)$ Spaces 

    Ullah, Kifayat؛ Khan, Hikmat؛ Arshad, Muhammad (University of Maragheh, 2018-11-01)
    In this paper, first we use an example to show the efficiency of $M$ iteration process introduced by Ullah and Arshad [4] for approximating fixed points of Suzuki generalized nonexpansive mappings. Then by using $M$ iteration ...

  • On Character Space of the Algebra of BSE-functions 

    Fozouni, Mohammad (University of Maragheh, 2018-11-01)
    Suppose that $A$ is a semi-simple and commutative Banach algebra. In this paper we try to characterize the character space of the Banach algebra $C_{rm{BSE}}(Delta(A))$ consisting of all  BSE-functions on $Delta(A)$ where ...

    The purpose of this paper is to introduce and study the concepts of fuzzy $e$-open set, fuzzy $e$-continuity and fuzzy $e$-compactness in intuitionistic fuzzy topological spaces. After giving the fundamental concepts of ...

  • On Generators in Archimedean Copulas 

    Najjari, Vadoud (University of Maragheh, 2018-11-01)
    This study after reviewing  construction methods of generators in Archimedean copulas (AC),  proposes several useful lemmas related with generators of AC. Then a new trigonometric Archimedean family will be shown which is ...

  • On Regular Generalized $delta$-closed Sets in Topological Spaces 

    Rajakumar, Somasundaram (University of Maragheh, 2018-11-01)
    In this paper a new class of sets called  regular generalized  $delta$-closed set (briefly rg$delta$-closed set)is introduced and its properties are studied. Several examples are provided to illustrate the behaviour of ...

  • On Some Properties of the Max Algebra System Over Tensors 

    Shojaeifard, Ali Reza؛ Afshin, Hamid Reza (University of Maragheh, 2018-11-01)
    Recently we generalized the max algebra system to the class of nonnegative  tensors. In this paper we give some basic properties for the left (right) inverse, under the new system. The existence of order 2 left (right) ...
