WebMay 29, 2024 · The arithmetic theory of binary quadratic forms originated with P. 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. 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
