Binary cubic forms

WebNov 8, 2024 · The least positive integers such that there exist rational integers representing the absolute values of a reduced binary quadratic form and a reduced binary cubic form can be calculated by the simple continued fractions of a quadratic irrationality and a cubic irrationality, respectively. WebFeb 7, 2024 · To prove Theorems 1 and 2, we will make use of the correspondence by Mordell between integer solutions of \(y^2=x^3+kB^2\) and certain integral binary cubic forms. The main strategy is to carry out a discriminant-lowering procedure on the set of the integral binary cubic forms.

WebFeb 1, 2010 · A reduction theory is developed for binary forms (homogeneous polynomials) of degrees three and four with integer coefficients. The resulting coefficient bounds simplify and improve on those in the literature, particularly in the case of negative discriminant.

WebNote such a polynomial could be referred to as an integral binary cubic form with triplicate central coe cients, but we shorten this to binary cubic form for conciseness. A binary cubic form is called projective if the Hessian of the cubic form is primitive, i.e. if gcd(a2 1 a 0a 2;a 0a 3 a 1a 2;a 2 2 a 1a 3) = 1: We say a binary cubic form is ... WebJul 30, 2010 · Delone and Faddeev, in 1940, showed that cubic rings are parameterized by equivalence classes of integral binary cubic forms. Birch, Merriman, Nakagawa, del Corso, Dvornicich, and Simon have all studied rings associated to binary forms of degree n for any n, but it has not previously been known which rings, and with what additional structure ...

Web0.0. The class numbers of binary forms of degree greater than three has been scarcely studied. It seems that the finiteness of class numbers proved by Birch and Merriman is the only general result. In the case of binary cubic forms, Davenport obtained asymptotic formulae for certain sums of class numbers.
