Cubic fourfolds, K3 surfaces, and rationality questions

Algebraic Geometry 2016-07-19 v2

Abstract

This is a survey of the geometry of complex cubic fourfolds with a view toward rationality questions. Topics include classical constructions of rational examples, Hodge structures and special cubic fourfolds, associated K3 surfaces and their geometric interpretations, and connections with rationality and unirationality constructions.
