Einstein hypersurfaces are “very rare” in rank-one symmetric spaces. Damek-Ricci spaces may be viewed as the closest and the most natural generalisations of noncompact rank-one symmetric spaces. We prove that no Damek-Ricci space admits an Einstein hypersurface.

Damek-Ricci空间的爱因斯坦超曲面

在一级对称空间中,爱因斯坦超曲面是“非常罕见的”。Damek-Ricci空间可以被视为非紧缩秩一对称空间的最接近,最自然的概括。我们证明没有Damek-Ricci空间承认爱因斯坦超曲面。
