SUMMARY:Exotic R^4's are unclassifiable
DESCRIPTION:Freedman Seminar \nSpeaker: Robert Gompf\, UT Austin \nTitle: Exotic R^4’s are unclassifiable \nAbstract: We will use descriptive set theory to show that there is a precise sense in which exotic R^4’s are unclassifiable. For other open manifolds\, we can reach a much higher level of unclassifiability. This is work in progress with Aristotelis Panagiotopoulos.
