## Osama Moaaz and Mahmoud A.E. Abdelrahman, On the Class of the Rational Difference Equations, Volume 2017, Number 4, Pages 46-55, 2017.

Abstract: In this paper we investigate the qualitative behavior of the solution of the class of the rational Difference Equations. Namely, we consider the stability, boundedness, and periodicity of the solution. We also give some interesting examples in order to verify our results. Keywords: Difference equations, equilibrium...

## S.Anita Shanthi, N.Thillaigovindan and R.Poovizhi, Separation axioms on fuzzy rough topological spaces, Volume 2017, Number 4, Pages 33-45, 2017.

Abstract: In this paper we introduce separation axioms on fuzzy rough topological spaces using the concept of fuzzy rough points and study some of their properties. We also discuss some properties of these spaces. Keywords: Fuzzy rough open and closed sets, fuzzy rough point, fuzzy rough subspace,...

Abstract: The first two hyper-Zagreb indices of a graph $G$ denoted, $HM_{1}(G)$ and $HM_{2}(G)$ are well known. Considering these hyper Zagreb indices, in this paper we computing the first two hyper-Zagreb indices and their polynomials of certain classes of windmill graphs such as french windmill graphs,...

## Omar M. Saad, Mervat M. Elshafei and Marwa M. Sleem, Interactive Approach for Multi-level Quadratic Fractional Programming Problems, Volume 2017, Number 4, Pages 1-13, 2017.

Abstract: This paper, present an Interactive decision making method for multi-level quadratic fractional programming \textbf{(MLQFP)} problems. The upper-level objective function is quadratic fractional problem in which both the numeratorand denominator of the objective function can be factorized into linear function, the second-level objective function is...
