Nonoscillation criteria for half-linear second-order difference equations
Nonoscillation criteria for the half-linear second-order difference equation Delta (r(k)Phi(Deltax(k))) + c(k)Phi (x(k+1)) = 0, Phi (x) := \x\(p-2)x, p >1 are established, These criteria are derived using the Riccati and variational technique. (C) 2001 Elsevier Science Ltd. All rights reserved.
