Lefschetz fibrations (in dimension 4) and open books (in dimension 3) encode symplectic and contact structures in a purely topological way, so that low-dimensional topology informs sympectic geometry. I will explain basic definitions and examples and state some fundamental theorems. (These tools will be needed in my Geometry/Topology seminar talk.)
