DESCRIPTION:Title: <a href="https://stable.researchseminars.org/talk/HAC/1
 /">On a class number formula of Hurwitz</a>\nby Özlem Imamoglu (ETH Züri
 ch) as part of Heilbronn Annual Conference 2020\n\n\nAbstract\nClass numbe
 r formulas have long and rich history. In a mostly forgotten paper\, Hurwi
 tz gave an infinite series representation for the class number of positive
  definite quadratic forms. In this talk I will give an overview of Hurwitz
 ’s formula and show how similar ideas can be used to give a formula in t
 he indefinite case as well as a class number formula for binary cubic form
 s.\n
