In §3 we return to our √ “unfinished theorems” about represen-tation of primes by |x2 − Dy2| when Z[ D] is a PID: using quadratic reciprocity, we can state and prove three bonus theorems which …

From the modern point of view, the key observation is that it has to do with whether or not 1 is a quadratic residue mod p. De nition 1. Let p be a prime and a be an integer. We say a is a …

Determine the primes p for which 7 is a quadratic residue of p. We want 1 = 7 p = ( 1) p 1 2 p 7 which happens if and only if ( 1) p 1 2 = p 7 = 1 or ( 1) p 1 2 = p 7 = 1: By direct computation we …
