| Abstract: | This paper studies the oscillation of all solutions of the equation where all the coefficients Pi,qk and rj are positive constants. On the basis of the work done by Cheng Wuanji in his,article "Qscillation Criteria for Higher Order Functional Differential Equation of Mixed Type"some more effective and practical necessary and sufficient conditions are established. |
