DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGeNT/8/">O
 n the negative Pell equation</a>\nby Carlo Pagano (University of Glasgow/M
 PIM Bonn) as part of Leiden Algebra\, Geometry\, and Number Theory Seminar
 \n\n\nAbstract\nHow often does the ring of integers of a real quadratic fi
 eld have a unit with norm -1? In 1995 Peter Stevenhagen proposed a precise
  conjectural asymptotic formula describing how many such real quadratic fi
 elds should be out there when counted by discriminant. I will discuss a jo
 int upcoming work with Peter Koymans where we establish Stevenhagen's conj
 ecture.\n
