我们考虑与维度 $n\!\ge\!2$ 的实双曲空间上的 Laplace--Beltrami 算子 $\Delta$ 相关的克莱因-戈登方程;由于 $\Delta$ 有光谱间隙,波动方程是我们研究的一个特例。经过仔细的核分析后,我们获得了一个大家庭的可接受夫妇的分散和斯特里哈茨估计。作为一个应用,我们用低正则性数据证明了相应的半线性方程的全局适定性结果。
We consider the Klein--Gordon equation associated with the Laplace--Beltrami operator $\Delta$ on real hyperbolic spaces of dimension $n\!\ge\!2$; as $\Delta$ has a spectral gap, the wave equation is a particular case of our study. After a careful kernel analysis, we obtain dispersive and Strichartz estimates for a large family of admissible couples. As an application, we prove global well--posedness results for the corresponding semilinear equation with low regularity data.
