Summary
| Description |
English: Plot of the number of real cubic fields of bounded discriminant up to 106, and the asymptotic distribution. Black line is the first order term of the asymptotic, green line includes the second order term, and blue crosses are the exact counts. Data by Michel Olivier available at [1]. Asymptotics from Bhargava–Shankar–Tsimerman, "On the Davenport–Heilbronn theorem and second order terms", arXiv:1005.0672. |
