Abstract
The authors consider difference equations of the form Delta (a(n)(Deltay(n))(alpha)) + phi (n, y(n),Deltay(n)) + q(n)f(y(n+1)) = 0, where a(n) > 0, q(n) > 0, f, and phi are continuous real valued functions, and uf(u) > 0 for u not equal 0. They give oscillation results for equation (E). Examples are included to illustrate the results. (C) 2001 Elsevier Sc ience Ltd. All rights reserved.
