Sufficient Conditions for Oscillations of Parabolic Partial Differential Equations

本文讨论一类多滞量中立抛物型偏微分方程解的振动性质 ,获得了其一切解振动的充分条件 ;指出了与普通抛物型偏微分方程质的差异 .

In this paper, we investigate oscillatory properties of solutions of certain parabolic partial differential equations and establish a series of sufficient conditions for oscillations of the equations. The results fully indicate that the oscillations are caused by delay. This is one important conclusion and hence, reveals the essential differences between the equations and those equations without delay.
