WebThe aim of this section is to generalize to the cubic case the well known correspondence between binary quadratic forms and quadratic number fields. These results are due to Davenport and Heilbronn (see [ 5] and [ 6 ]). Before stating and proving the main theorem, we need a few preliminary results. WebDec 10, 2002 · ternary cubic forms, but rather to binary cubic forms (as was shown by Delone-Faddeev [4]), this indicates that we should perhaps slice away one layer of the 3 × 3 × 3 cube to retain only a 2 × 3 × 3 box of integers, so that the one SL 3 × SL 3-invariant is a binary cubic form, while the other two dimensions

WebMay 16, 2024 · We also count the number of abelian monic binary cubic forms with integer coefficients up to a natural equivalence relation ordered by the so-called Bhargava–Shankar height. Finally, we prove an assertion characterizing the splitting field of 2-torsion points of semi-stable abelian elliptic curves.
