The scalar difference equation xn+1 = fn(xn, xn−1, · · · , xn−k) may exhibit symmetries in its form that allow for reduction of order through substitution or a change of variables. Such form… (More)

We study the dynamics of the positive solutions of the exponential difference equation xn+1 = xn−1ean−xn−1−xn where the sequence {an} is periodic. We find that qualitatively different dynamics occurs… (More)

Each solution{xn} of the equation in the title is either eventually periodic with period 3 or e it converges to zero—which case occurs depends on whether the ratio of the initial values of{xn} is… (More)
