DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GANT/84/">En
 umerative geometry of curves via tautological classes</a>\nby Georgios Pol
 itopoulos (Leiden University) as part of Greek Algebra & Number Theory Sem
 inar\n\n\nAbstract\nEnumerative geometry has been at the heart of geometry
  for more than two millennia. Its aim is to answer questions of the follow
 ing kind: how many geometric objects $X$ there are satisfying conditions $
 Y_1\,\\ldots\,Y_n$. In this talk\, I will begin with a brief history of en
 umerative geometry before discussing modern tools for addressing such ques
 tions. In particular\, I will introduce moduli spaces\, their intersection
  theory\, and tautological classes. I will then use these notions to prese
 nt joint work with Adrien Sauvaget and David Holmes on the enumerative geo
 metry of stable curves.\n
