论文摘要
让$ s $是配备Laplace-Beltrami操作员$δ$的Damek-Ricci空间。在本文中,我们将$δ$的所有本征函数通过球,球和壳平均值表示,因为(球体,球或外壳)倾向于无穷大。
Let $S$ be a Damek-Ricci space equipped with the Laplace-Beltrami operator $Δ$. In this paper we characterize all eigenfunctions of $Δ$ through sphere, ball and shell averages as the radius (of sphere, ball or shell) tends to infinity.
