Abstract:
Let M be a closed irreducible Riemannian 3-manifold such that π1(M) is word hyperbolic, and p: X→ M the universal covering. Suppose that X has the Riemannian metric induced form that on M via p. In this paper, we will show that any Jordan curve in the boundary ∂X of X spans a properly embedded least area plane in X.Mathematics Subject Classiffications (2000). Primary 57M50; secondary 53A10
