| Abstract: | The second order neutral functional differential equations of mixed type:d2d2/dt2x(t) +cx (t-h) +c * x (t+h * )]+qx(t-g) +px(t+g * ) = 0is studied, where c,c*,h,h*, p, q are real numbers, g and g* are positive constants, and some new criterias for the oscillation of those equations are established. The results in this paper improve all theorems inl]. |
