Book Description:

Given a prime p, a group is called residually p if the intersection of its ppower index normal subgroups is trivial. A group is called virtually residually p if it has a finite index subgroup which is residually p. This gives evidence for the conjecture (Thurston) that fundamental groups of $3$manifolds are linear groups.
