WebAbstract. Let Γ Γ be a lattice in SO0(n,1) S O 0 ( n, 1). We prove that if the associated locally symmetric space contains infinitely many maximal totally geodesic subspaces of dimension at least 2 2, then Γ Γ is arithmetic. This answers a question of Reid for hyperbolic n n -manifolds and, independently, McMullen for hyperbolic 3 3 -manifolds. WebOct 12, 2024 · So that gives you the first totally geodesic hypersurface in some finite cover of the given thing. And since the hypersurface is the same type of lattice, there is a finite cover of it that has a totally geodesic hypersurface by the same argument. There is a single finite cover of the original thing doing both at once. gold pinboard https://mrhaccounts.com
