DESCRIPTION:Speakers: Pietro Capovilla (University of Cyprus)\n\nObersemin
 ar Differentialgeometrie\nI will present an explicit construction of close
 d oriented aspherical smooth 4-manifolds realizing every non-negative Eule
 r characteristic. This family of manifolds saturates Hopf-Thurston conject
 ure on the Euler characteristic of aspherical manifolds\, as well as Gromo
 v-Lück inequality on their geography.\n\nhttps://math-events.uni-bonn.de/
