Abstract:
Consider the neutral delay differential equation d d t [ x ( t ) - P ( t ) x ( t - t ) ] + Q ( t ) x ( t - d ) = 0 , ? ? ? t = t 0 ( * ) Where P , Q ? C ( [ t 0 , 8 ] , R + ) , t ? ( 0 , 8 ) and d ? R + . We obtain several sufficient conditions for the oscillation of all solutions of Eq. (*) without the restriction ? t 0 8 Q ( s ) d s = 8 .
