Abstract
In this paper, we will use Kahn and Markovic’s immersed almost totally geodesic surfaces to construct certain immersed π1-injective 2-complexes in closed hyperbolic 3-manifolds. Such 2-complexes are locally almost totally geodesic except along a 1-dimensional subcomplex. By using Agol’s result that the fundamental groups of closed hyperbolic 3-manifolds are vitually compact special, and other works on geometric group theory, we will show that any closed hyperbolic 3-manifold virtually contains any prescribed subgroup in the homological torsion. More precisely, our main result is, for any finite abelian group A, and any closed hyperbolic 3-manifold M,M admits a finite cover N, such that A is a direct summand of Tor(H1(N;Z)).
