SUMMARY:Geometry & Topology Seminar
CLASS:PUBLIC
DESCRIPTION:MICHAEL ALBANESE\, UQAM\n\n\"THE YAMABE INVARIANT OF NON-KÄHLE
 R SURFACES\"\n\nThe Yamabe invariant is a real-valued diffeomorphism invar
 iant coming\nfrom Riemannian geometry. Using Seiberg-Witten theory\, LeBru
 n showed\nthat the sign of the Yamabe invariant of a Kähler surface is\nd
 etermined by its Kodaira dimension. We consider the extent to which\nthis 
 remains true when the Kähler hypothesis is removed.\n\nThis seminar will 
 be held jointly online and in person:
