WebThis chapter discusses the equations of binary cubic forms. The number of classes of binary cubics with given discriminant is finite. The chapter also discusses the integer … WebReduction of binary cubic and quartic forms there will be two equivalent reduced forms (di ering only in the sign of b). This non-uniqueness, which could of course be avoided by insisting that b> 0 when either equality holds, will not be at all important in the sequel. To reduce a given form, we may choose to operate directly on the coe cients

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 … A binary form (of degree n) is a homogeneous polynomial Σ i=0 ( i)an−ix y = anx + ( 1)an−1x y + ... + a0y . The group SL2(C) acts on these forms by taking x to ax + by and y to cx + dy. This induces an action on the space spanned by a0, ..., an and on the polynomials in these variables. An invariant is a polynomial in these n + 1 variables a0, ..., an that is invariant under this action. More generally a covariant is a polynomial in a0, ..., an, x, y that is invariant, so an invariant is …
