DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HAC/1/">On a
  class number formula of Hurwitz</a>\nby Özlem Imamoglu (ETH Zürich) as 
 part of Heilbronn Annual Conference 2020\n\n\nAbstract\nClass number formu
 las have long and rich history. In a mostly forgotten paper\, Hurwitz gave
  an infinite series representation for the class number of positive defini
 te quadratic forms. In this talk I will give an overview of Hurwitz’s fo
 rmula and show how similar ideas can be used to give a formula in the inde
 finite case as well as a class number formula for binary cubic forms.\n
