Abstract

We use Minimal model theory to link birational maps of log surfaces (log contractions) to equidimensional fibrations of elliptic threefolds. In particular we give a necessary and sufficient condition for an elliptic threefold X → S to be birationally equivalent to an equidimensional elliptic fibration
