Abstract: An covered foliation is a special type of taut foliation on a manifold: one for which holonomy is defined for all transversals and all time. The universal cover of a manifold with such a foliation can be partially compactified by a cylinder at infinity, somewhat analogous to the sphere at infinity of a hyperbolic manifold. The action of on this cylinder decomposes into a product by elements of . The action on the factor of this cylinder is rigid under deformations of the foliation through covered foliations. Such a foliation admits a pair of transverse genuine laminations whose complementary regions are solid tori with finitely many boundary leaves, which can be blown down to give a transverse regulating pseudoAnosov flow. These results all fit in an essential way into Thurston's program to geometrize manifolds admitting taut foliations.
