SUMMARY:Complex structures on 4-manifolds
CLASS:PUBLIC
DESCRIPTION:LUCA DI CERBO\, UNIVERSITY OF FLORIDA\n\nA well-known conjectur
 e of Dennis Sullivan (Abel Prize 2022) asserts\nthat a hyperbolic n-manifo
 ld cannot admit a complex structure. This\nconjecture is known to be true 
 in dimension four (Toledo\, Carlson\,\nLeBrun). In this talk\, I will outl
 ine a new proof of the fact that a\nhyperbolic 4-manifold cannot support a
  complex structure. This new\nproof has some nice features\, and it genera
 lizes to show that all\nextended graph 4-manifolds with at least one pure 
 real-hyperbolic\npiece cannot support a complex structure.  This is joint
  work with M.\nAlbanese.\n\nMC 5417
