摘要
讨论一类非线性抛物型时滞偏微分方程组解的振动性,利用积分不等式和泛函微分方程的某些结果,获得了该类方程组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。
The oscillation of solutions for a class of systems of nonlinear parabolic delay partial differential equations are studied. Some sufficient conditions are obtained for oscillation of the systems by making use of the integral inequalities and some results of the functional differential equations. The results fully indicate that the oscillation are caused by delay.
