中立型双曲方程解的强迫振动性

Forced Oscillations of the Solutions of Hyperbolic Equations of Neutral Type

本文获得了中立型双曲方程解振动的充分条件。其中是具有逐片光滑边界的有界区域，△是拉普拉斯算符。

We have discussed the forced oscillations of the solutions of hyperbolic equation of neutral typeof the formwhere Ω is a bounded domain in R￣n with a piecewise smooth boundary,sufficient conditions are obtained for the forced oscillations of the solutions of the equation.
