某些具有偏差变元的抛物型方程的解的振动性

Oscillations of Some Parabolic Equations with Deviation Arguments

探讨了某些具有偏差变元的抛物型方程解的振动性 ,得到这些方程解为振动的充分条件 ,以扩充了傅希林 (1 994) ,崔宝同 (1 996) ,陈宁 (1 999)文中的某些定理 ,亦是作者 1 999年文的继续 ,主要结果是定理 2、定理 3与定理 5。

Discusses the oscillation of solutions of some Parabolic equations with deviationg arguments.By extending some theorems in [1],[2] and [3],the suffcient conditions for the Oscillation of solutions of these equstions is obtained.This paper continues for [3].The main results are theorem 2,theorem 3 and theorem 5.
