On Thurston's Euler class one conjecture


In 1976, Thurston proved that taut foliations on closed hyperbolic 3-manifolds
have Euler class of norm at most one, and conjectured that, conversely, any Euler class with
norm equal to one is Euler class of a taut foliation. We construct counterexamples to this
conjecture and suggest an alternative conjecture.
