On oscillation of difference equations with bounded phi-Laplacian
Oscillation of second order difference equations with bounded phi-Laplacian is studied by comparing it with the discrete Emden-Fowler difference equation. Analogues and discrepancies in behavior of solutions of these equations are also presented and a comparison with the continuous case is given. (C) 2011 Elsevier Ltd. All rights reserved.
