Archivum Mathematicum

In this paper, the oscillation criteria for solutions of the neutral delay differential equation (NDDE) y ( t ) - p ( t ) y ( t - τ ) ( n ) + α Q ( t ) G y ( t - σ ) = f ( t ) has been studied where p ( t ) = 1 or p ( t ) 0 , α = ± 1 , Q C [ 0 , ) , R + , f C ( [ 0 , ) , R ) , G C ( R , R ) . This work improves and generalizes some recent results and answer some questions that are raised in [1].
