Geometry and Topology Seminar

Symplectic and exotic 4-manifolds via positive factorizations
R. Inanc Baykur, Department of Mathematics and Statistics, University of Massachusetts
We will discuss new ideas and techniques for producing positive Dehn twist factorizations of surface mapping classes which yield novel constructions of interesting symplectic and smooth 4-manifolds, such as small symplectic Calabi-Yau surfaces and exotic rational surfaces, via Lefschetz fibrations and pencils.
