Motivated from Lefschetz hyperplane theorem, Donaldson showed that every symplectic 4-manifold admits the structure of a pencil whose fibers are symplectic submanifolds. Since then these pencils have been widely used to translate geometric problems in symplectic geometry into problems in mapping class groups. This talk will be a survey about Lefschetz pencils and their relation with the topology of symplectic 4-manifolds.
