Einstein hypersurfaces of Damek-Ricci spaces
arXiv:2104.09211 · doi:10.1016/j.geomphys.2021.104278
Abstract
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.
