摘要:讨论了一类非线性抛物型时滞偏微分方程系统的振动性,利用空间平均法和泛函微分方程的某些结果,获得了该类系统在第1类边值条件下所有解振动的若干充分条件.结论充分表明振动是由时滞量引起的.

关键词: 非线性, 抛物型偏微分方程系统, 时滞, 振动

Abstract: The oscillation for a class of systems of nonlinear parabolic delay partial differential equations is studied.Some sufficient conditions are obtained for oscillation of all solutions of the systems under first boundary value conditions via the method of spatial average and some results of the functional differential equations.The results fully indicate that the oscillation is caused by delay.

Key words: nonlinear, systems of parabolic partial differential equation, delay, oscillation
