English Abstract

In this thesis we will investigate the dynamical behavior of the following rational di erence equation ? n +1) = ( (a+B xn)+γxn-k)/(A+B xn+Cxn-k) where the parametersa, β,γ and A, B, C and the initial conditions ?- k, …, ?-1, ?0 are non-negative real numbers, and the denominator is nonzero. Our concentration here, is on the global stability, the periodic character, the analysis of semi-cycles and the invariant intervals of the positive solution of the above equation It is worth to mention that our divergence equation is the general case of the rational equation which is studied by Kulenvic and Ladas in their monograph (Dynamics of Second Order Rational Deference Equation with Open Problems and Conjectures, 2002).
