(1)d = f(d)f(d),其中f(d)是最大正整数,其中f(d)= d/f(d)2是判别式。整数f(d)称为判别式d的导体。如果f(d)= 1,则判别式d称为基本判别式。判别式d是基本的,当且仅当d是奇数且无平方或d是偶数,d/4是无平方且d/4 = 2或3(mod 4)。我们注意到,判别式f(d)是基本的,使得f(f(d))= 1且f(f(d))= f(d)。如果d = f ′f ′,其中f ′是一个基本判别式,f ′是一个正整数,则f ′ = f(d),f ′ = f(d)。判别式f(d)被称为与判别式d相关联的基本判别式。如果d1和d2是判别式,那么d1 d2也是判别式。我们有
(1) d = ∆(d)f(d), where f(d) is the largest positive integer for which ∆(d) = d/f(d)2 is a discriminant. The integer f(d) is called the conductor of the discriminant d. The discriminant d is called fundamental if f(d) = 1. A discriminant d is fundamental if and only if d is odd and squarefree or d is even, d/4 is squarefree and d/4 ≡ 2 or 3 (mod 4). We note that the discriminant ∆(d) is fundamental so that f(∆(d)) = 1 and ∆(∆(d)) = ∆(d). If d = ∆′f ′, where ∆′ is a fundamental discriminant and f ′ is a positive integer, then ∆′ = ∆(d) and f ′ = f(d). The discriminant∆(d) is called the fundamental discriminant associated with the discriminant d. If d1 and d2 are discriminants then d1d2 is also a discriminant. We have
