Özet
In this manuscript, we study oscillatory behaviour of the following forced nonlinear difference equation:Δm (yn + pn yn - σ) + qn f (yn - τ) = rn .Unlike to the most of the existing results in the literature, we give some new criteria which do not depend on the usual restrictions on the terms pn, qn and rn. We consider the cases where pn is eventually of fixed sign and oscillatory, and qn is of eventually fixed sign and oscillatory. We also give various numerical simulations by using the MATLAB programming to support the results. © 2009 Elsevier Ltd. All rights reserved.
