Thank you. ... Binary Quadratic Forms... Cohen, A Course in Computational Algebraic NUmber Theory... Franz Halter-Koch, Quadratic Irrationals. WebAn integral binary quadratic form is an expression ax 2+bxy+cy in Z[x;y]. The discriminant of the form is = b2 4ac. If <0, the form is de nite. It is called primitive if gcd(a;b;c) = 1. 4. It is a fact of the theory of quadratic forms that de nite forms take only values of a single sign. This is a consequence of the fact that, over R, any

Web1.For D = 1, with = 4, we have two reduced binary quadratic forms x2 + y2 and x2 y2. Applying the map ’ FI to them yields the same ideal (1;i) = Z[i] along with a sign 1. Conversely, applying ’ IF to I = (1;i) and the sign +1 yields the quadratic form N(x + iy) N(1) = x2 + y2, while applying ’ IF to I = (1;i) and the sign 1 yields the ... Webof binary quadratic forms can be viewed as groups, at a time before group theory formally existed. Beyond that, he even de ned and calculated genus groups, which are essentially quotient groups, that explain which congruence classes of numbers can be represented by given sets of forms.

Fermat, who proved that any prime number of the form $ 4k + 1 $ can be represented as the sum of two squares of integers. The theory of quadratic forms was completed by J.L. Lagrange and by C.F. Gauss.
