  • Domination Number of Nagata Extension Ring 

    Shariatinia, Abbas (Islamic Azad University of Arak, 2019-03-01)
    Aََََbstract:Let R is a commutative ring whit Z(R) as the set of zero divisors. The total graph of R, denoted by T ((R)) is the (undirected) graph with all elements of R as vertices, and two distinct vertices are adjacent ...

  • Fuzzy Farthest Points and Fuzzy Best Approximation Points in Fuzzy Normed Spaces 

    Mazaheri Tehrani, Hamid؛ Mouavi Shams Abad, S. M؛ Dehghan, M. A؛ Bizhanzadeh, Z. (Islamic Azad University of Arak, 2019-03-01)
    In this paper we define fuzzy farthest points, fuzzy best approximation points and farthest orthogonality in fuzzy normed spaces and we will find some results. We prove some existence theorems, also we consider fuzzy Hilbert ...

  • The Iterative Method for Solving Non-Linear Equations 

    Mansouri, Parvaneh (Islamic Azad University of Arak, 2019-03-01)
    In this paper, we have combined the ideas of the False Position (FP) and Artificial Bee Colony (ABC) algorithms to find a fast and novel method for solving nonlinear equations. Additionally, to illustrate the efficiency ...
