摘要
This paper studies a class of nonlinear second order difference equations of the type x(n+1) = f(x(n), x(n-1))/x(n), where f is symmetric and monotonic with initial conditions x(-1), x(0) being positive real numbers. Some sufficient conditions under which every positive solution of such equation converges to a period two solution or to the cycle {0, infinity} are established.
