On the oscillatory behavior for a certain class of third order nonlinear delay difference equations

Electronic Journal of Qualitative Theory of Differential Equations, 2010
By employing the generalized Riccati transformation technique, we will establish some new oscillation criteria for a certain class of third order nonlinear delay difference equations. Our results extend and improve some previously obtained ones.
