THE DICHOTOMY CHARACTER OF
WITH PERIOD-TWO COEFFICIENTS
We extend the known results of the nonautonomous difference equation in the title to the situation where (i) the parameters βn and γn are period-two sequences of nonnegative real numbers with γn not identically zero; (ii) the parameters An and Bn are period-two sequences of positive real numbers; and (iii) the initial conditions x−1 and x0 are such that x−1,x0 ∈ [0, ∞) and x−1 + x0 ∈ (0, ∞).
