DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ZAG/49/">Sin
 gularities and divisors in the moduli space of surfaces</a>\nby Julie Rana
  (Lawrence University) as part of ZAG (Zoom Algebraic Geometry) seminar\n\
 n\nAbstract\nThe KSBA moduli space of stable surfaces (surfaces with slc s
 ingularities and ample canonical class) is a natural compactification of G
 ieseker's moduli space of surfaces of general type. In contrast with the m
 oduli space of curves\, very little is known about the birational geometry
  of KSBA moduli spaces\; indeed\, there are very few examples of divisors 
 in KSBA moduli spaces. I will give an example of a divisor in the moduli s
 pace of quintic surfaces corresponding to surfaces with cyclic quotient si
 ngularities. I also discuss joint work with Giancarlo Urz\\'ua where we gi
 ve bounds that help to narrow the search.\n
