Abstract

Suppose F is a compact orientable surface, K is a knot in F×I, and (F×I)surg is the 3–manifold obtained by some nontrivial surgery on K. If F×{0} compresses in (F×I)surg, then there is an annulus in F×I with one end K and the other end an essential simple closed curve in F×{0}. Moreover, the end of the annulus at K determines the surgery slope.

An application: Suppose M is a compact orientable 3–manifold that fibers over the circle. If surgery on KM yields a reducible manifold, then either

* the projection KMS1 has nontrivial winding number,

* K lies in a ball,

* K lies in a fiber, or

* K is cabled.
