R-covered foliations of hyperbolic 3-manifolds
We produce examples of taut foliations of hyperbolic 3-manifolds which
are R-covered but not uniform --- ie the leaf space of the universal
cover is R, but pairs of leaves are not contained in bounded
neighborhoods of each other. This answers in the negative a conjecture
of Thurston `Three-manifolds, foliations and circles I'
(math.GT/9712268). We further show that these foliations can be chosen
to be C^0 close to foliations by closed surfaces. Our construction
underscores the importance of the existence of transverse regulating
vector fields and cone fields for R-covered foliations. Finally, we
discuss the effect of perturbing arbitrary R-covered foliations.
