一类半线性波方程的多周期解结果

Multiplicity Results for a Class of Semilinear Wave Equation

本文利用度理论和文[1]中截去非零核空间的方法,得到了一类非线性项无单调性假设的、半线性波方程在强迫振动下的多周期解结果。

In this paper, with degree theory and method which reduced kernelof ?_(tt)-?_(xx) to o in paper[1], we obtained the multiplicity period resultfor a class of forced semilinear wave equation without assumpition ofmonotonicity.
