Title: Rational global homotopy theory

Abstract: Global homotopy theory has recently been extensively developed by Schwede. It is a framework that makes sense of homotopy types encoding compatible actions by all (say finite) groups. As in more classical situations, rationally the global homotopy category simplifies. However in contrast to genuine G-spectra it does not split. I will discuss a rather explicit equivalence to an easily defined derived category via a geometric fixed points construction.
