DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OBAGS/13/">C
 omputing limit mixed Hodge structures</a>\nby Emre Can Sertöz (Hannover) 
 as part of ODTU-Bilkent Algebraic Geometry Seminars\n\n\nAbstract\nConside
 r a smooth family of varieties over a punctured disk that is extended to a
  flat family over the whole disk\, e.g.\, consider a 1-parameter family of
  hypersurfaces with a central singular fiber. The Hodge structures (i.e. p
 eriods) of smooth fibers exhibit a divergent behavior as you approach the 
 singular fiber. However\, Schmid's nilpotent orbit theorem states that thi
 s divergence can be "regularized" to construct a limit mixed Hodge structu
 re. This limit mixed Hodge structure contains detailed information about t
 he geometry and arithmetic of the singular fiber. I will explain how one c
 an compute such limit mixed Hodge structures in practice and give a demons
 tration of my code.\n
