  • A local approach to the entropy of countable fuzzy partitions 

    R. Ghasemkhani, R.؛ Mohammadi, u. (University of Mazandaranدانشگاه مازندران, 2017-01-01)
    This paper de nes and investigates the ergodic proper-ties of the entropy of a countable partition of a fuzzy dynamical sys-tem at different points of the state space. It ultimately introducesthe local ...

  • On the determination of eigenvalues for differential pencils with the turning point 

    Neamaty, A.؛ Khalili, Y. (University of Mazandaranدانشگاه مازندران, 2017-01-01)
    In this paper, we investigatethe boundary value problem for differential pencils on the half-linewith a turning point. Using a fundamental system of solutions, wegive a asymptotic distribution of eigenvalues.

  • Characterizations of Slant Ruled Surfaces in the Euclidean 3-space 

    Önder, Mehmet؛ Kaya, Onur (University of Mazandaranدانشگاه مازندران, 2017-01-01)
    In this study, we give the relationships between the conical curvatures of ruled surfaces generated by the unit vectors of the ruling, central normal and central tangent of a ruled surface in the Euclidean 3-space E^3. We ...

  • Warped product and quasi-Einstein metrics 

    Pal, Buddhadev؛ Bhattacharyya, Arindam؛ Dey, Santu (University of Mazandaranدانشگاه مازندران, 2017-01-01)
    Warped products provide a rich class of physically significant geometric objects. Warped product construction is an important method to produce a new metric with a base manifold and a fibre. We construct compact base ...

  • Reduction of Differential Equations by Lie Algebra of Symmetries 

    Hejazi, S. Reza (University of Mazandaranدانشگاه مازندران, 2017-01-01)
    The paper is devoted to an application of Lie group theory to differential equations. The basic infinitesimal method for calculating symmetry group is presented, and used to determine general symmetry group of some ...
