| Abstract: | By means of the averaging technique,we obtain new oscillation criteria for second order neutral differential equation a(t) (x(t) + p(t) x(t -τ))']' + q(t) fx(t) ,x(t -σ) ]g'x'(t) ] = 0.These results are different from most known ones in the sense that they are based on the information only on a sequence of subintervals of t0 ,∞), rather than on the whole half-linear. |
