DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Geolis/89/">
 The Yamabe Invariant of Complex Surfaces</a>\nby Michael Albanese (Univers
 ité du Québec à Montréal) as part of Geometria em Lisboa (IST)\n\n\nAb
 stract\nThe Yamabe invariant is a real-valued diffeomorphism invariant com
 ing from Riemannian geometry. Using Seiberg-Witten theory\, LeBrun showed 
 that the sign of the Yamabe invariant of a Kähler surface is determined b
 y its Kodaira dimension. We consider the extent to which this remains true
  when the Kähler hypothesis is removed. This is joint work with Claude Le
 Brun.\n
