利用平均法和微分不等式技巧来讨论非线性中立型抛物微分方程组在两类边界条件下解强迫振动性问题,建立了该方程组在一定条件下所有解振动和强振动的一些易于判别的充分条件。
In this paper, we discuss the forced oscillation of a class of nonlinear neutral parabolic differential equations with two kinds of boundary conditions by using the method of average and the differential inequality technique. Some sufficient conditions which are easily checked are established for the oscillation and the forced oscillation of all solutions of the equations.
