DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGeNT/19/">
 Separating periods of quartic surfaces</a>\nby Emre Sertöz (Leibniz Unive
 rsität Hannover) as part of Leiden Algebra\, Geometry\, and Number Theory
  Seminar\n\n\nAbstract\nWe give an effective lower bound on the distance b
 etween two distinct periods of a given quartic surface defined over the al
 gebraic numbers. The main ingredient is the determination of height bounds
  on components of the Noether--Lefschetz loci. This makes it possible to s
 tudy the Diophantine properties of periods of quartic surfaces and to cert
 ify a part of the numerical computation of their Picard groups. This is jo
 int work with Pierre Lairez.\n
