Başlık:
Arithmeticity of complex surfaces  with special attention to Kodaira  
fibrations

Özet:
In this talk I shall attempt to show that whether or not a complex surface
$S$ can be defined by polynomials
with coefficients in a number field depends only on the holomorphic  
universal covers of certain Zariski open subsets $U\subset S$. In the  
particular case of Kodaira fibrations $U$ can be taken to be the whole  
surface $S$.
  This characterization of arithmeticity in terms of universal covers is
   very much in contrast with the corresponding situation in complex  
dimension one, where the universal cover is always the unit disk.

    This is joint work with Sebasti\'n Reyes-Carocca.
