Abstract

We show that if L\mathcal{L} is a codimension-one lamination in a finite volume hyperbolic 3-manifold such that the principal curvatures of each leaf of L\mathcal{L} are all in the interval (δ,δ)(-\delta ,\delta) for a fixed δ[0,1)\delta\in[0,1) and no complimentary region of L\mathcal{L} is an interval bundle over a surface, then each boundary leaf of L\mathcal{L} has a nontrivial fundamental group. We also prove existence of a fixed constant δ0>0\delta_0 > 0 such that if L\mathcal{L} is a codimension-one lamination in a finite volume hyperbolic 3-manifold such that the principal curvatures of each leaf of L\mathcal{L} are all in the interval (δ0,δ0)(-\delta_0 ,\delta_0) and no complimentary region of L\mathcal{L} is an interval bundle over a surface, then each boundary leaf of L\mathcal{L} has a noncyclic fundamental group.
