Trisections and Ozsvath-Szabo cobordism maps

Abstract: Given a smooth, oriented four-manifold X with connected boundary, we'll demonstrate how to use the data of a trisection (in particular, its diagrammatic and fibration structures) to compute the induced cobordism maps in Heegaard Floer homology.
