As a consequence, the classification theory for Lefschetz pencils in the context of symplectic topology is analogous to the corresponding theory arising in differential topology.Published by Geometry and Topology Monographs at http://www.maths.warwick.ac.uk/gt/GTMon7/paper11.abs.htmlSymplectic Geometry57R17text
