Abstract:

Let $M$ and $N$ be two compact orientable $3$-manifolds, we say that $M \geq N$, if there is a degree one map from $M$ to $N$. This gives a way to measure the complexity of $3$-manifolds. The main purpose of this paper is to give a positive answer to the following conjecture: if there is an infinite sequence of degree one maps between Haken manifolds, then eventually all the manifolds are homeomorphic to each other. More generally, we prove a theorem which says that any infinite sequence of degree one maps between the so-called "geometric $3$-manifolds" must eventually become homotopy equivalences.
