  • Centers, Commutators and Abelianization of Crossed Squares 

    Çetin, Selim (University of Mazandaranدانشگاه مازندران, 2018-09-01)
    In this work we introduce the center of a cat2-group and some related structures in the sense of [7, 8]. Furthermore, by using the equivalence between crossed squares and cat2-groups, we also introduce the center of a ...

  • Intuitionistic fuzzy G-modules relative with a t-norm 

    Talaee, Behnam؛ Alinia, Maryam (University of Mazandaranدانشگاه مازندران, 2018-09-01)
    Fuzzy G-modules of fuzzy modules with respect to a t-norm were studied by some authors. Here we introduce the concept of intuitionis- tic fuzzy G-modules with respect to a t-norm and study some properties

  • Orthogonality of Homogeneous geodesics on the tangent bundle 

    Tondro Vishkaei, H.؛ Chavosh Khatamy, Reza؛ Toomanian, M. (University of Mazandaranدانشگاه مازندران, 2018-09-01)
    Let  $xi=(Gtimes_{K} mathcal{G} / mathcal{K}, rho_{xi}, G/K,mathcal{G} / mathcal{K})$  be the associated bundle and $tau_{G/K}=(T_{G/K},pi_{G/K},G/K, textrm{R}^{m})$ be the tangent bundle of special examples of odd dimension ...

  • A method to consider Non-Discretionary factors in Data Envelopment Analysis 

    Fallah Jelodar, Mehdi (University of Mazandaranدانشگاه مازندران, 2018-09-01)
    The technique for efficiency measurement known as Data Envelopment Analysis (DEA) has been extended to allow on-discretionary inputs that affect production. Several methods exist for measuring efficiency to control these ...

  • Existence of solution for semilinear elliptic equations via sub-super solutions method 

    Karamali, Gholamreza؛ Jashnani, Hamidreza (University of Mazandaranدانشگاه مازندران, 2018-09-01)
    In this paper, we considered a class of semilinear elliptic equations and extended some results about the method of sub-supper solutions to obtain new results for the generalized semi-linear elliptic equations via Schauder's ...
