Abstract
In this paper we give an explicit construction of a symplectic Lefschetz fibration whose total
space is a smooth compact four dimensional manifold with a prescribed fundamental group. We
also study the numerical properties of the sections in symplectic Lefschetz fibrations and their
relation to the structure of the monodromy group.
