We will discuss new ideas and techniques for producing positive听Dehn twist factorizations of surface mapping classes (joint work with听Mustafa Korkmaz) which yield novel constructions of interesting symplectic听and smooth 4-manifolds, such as small symplectic Calabi-Yau surfaces and听exotic rational surfaces, via Lefschetz fibrations and pencils.
