Query: Collisions at infinity in hyperbolic manifolds   For a complete, finite volume real hyperbolic n-manifold M, we investigate
the map between homology of the cusps of M and the homology of $M$. Our main
result provides a proof of a result required in a recent paper of Frigerio,
Lafont, and Sisto.
