Seminar: Class numbers of real quadratic fields

Time:

Venue/Location: Phòng C102, VIASM, 157 phố Chùa Láng, Hà Nội

Seminar: Class numbers of real quadratic fields (part 2)

Báo cáo viên: Ngô Trung Hiếu (Institute of Mathematics Hanoi)

Tóm tắt: This is a continuation of our previous talk. We discuss the reduction theory of indefinite binary quadratic forms. We study two countings of Siegel for class numbers of real quadratic fields, weighted by the regulators and ordered by discriminants.
