Resumen de Totally geodesic submanifolds of Damek–Ricci spaces

Sinhwi Kim, Yuri Nikolayevsky, Jeong Hyeong Park

• We classify totally geodesic submanifolds of Damek–Ricci spaces and show that they are either subgroups (“smaller” Damek–Ricci spaces) or isometric to rank-one symmetric spaces of negative curvature.
