DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CIRGET/97/">
 Compact K\\"ahler threefold with nef anticanonical line bundle</a>\nby Xia
 ojun Wu (Universität Bayreuth) as part of CRM - Séminaire du CIRGET / G
 éométrie et Topologie\n\nLecture held in PK-5115.\n\nAbstract\nIn my tal
 k\, I will discuss a recent collaboration with Shin-ichi Matsumura on comp
 act Kähler threefolds with nef anticanonical line bundles. Thanks to the 
 breakthrough result of Cao-Höring\, we can focus on the non-projective ca
 se. Using the Kähler threefold MMP developed by Höring-Peternell\, we ha
 ve shown that there are only three possibilities for such manifolds: (1) C
 alabi-Yau manifolds\; (2) projectivizations of numerical flat vector bundl
 es over a torus\; (3) products of K3 surfaces with projective lines. I wil
 l begin by reviewing the arguments of Cao-Höring and then explain the dif
 ferent ingredients we used to establish our results in the Kähler setting
