We will sketch the proof of quadratic reciprocity by manipulating some special complex numbers. Speci cally, let p= e2ˇi=p. Then, p is a primitive pth-root of unity, in the sense that p p= 1 and r …
The quadratic reciprocity has been vastly generalized to the Artin reciprocity, in the framework of class field theory. Hopefully we will be able to give another highbrow proof after introducing …
Quadratic Reciprocity is arguably the most important theorem taught in an elementary number theory course. Since Gauss’ original 1796 proof (by induction!) appeared, more than 100 …
QUADRATIC RECIPROCITY I PETE L. CLARK We now come to the most important result in our course: the law of quadratic reciprocity, or, as Gauss called it, the aureum theorema (“golden …
The law of quadratic reciprocity (the main theorem in this project) gives a precise relation- ship between the “reciprocal” Legendre symbols (p/q) and (q/p) where p,q are distinct odd primes.
We can therefore state the Law of Quadratic Reciprocity as p q = 8 >> >> < >> >>: q p if p 1 (mod 4) or q 1 (mod 4); q p if p q 3 (mod 4): Daileda Quadratic Reciprocity
Theorem (Quadratic Reciprocity). For odd primes p;qwe have p q q p = ( 1)p 1 2 ( 1) q 1 2 where l is the Legendre symbol, a l = 1 according as x2 a(l) has a solution or not. Proof 1. Let ˜be the …
Let bbe an integer; an integer acoprime to bis called a quadratic residue modulo bif a≡ x 2 mod bfor some integer x, and a quadratic nonresidue modulo botherwise.
The law of quadratic reciprocity (the main theorem in this project) gives a precise relation- ship between the \reciprocal" Legendre symbols (p=q) and (q=p) where p;qare distinct odd primes.
Now we can start talking about the quadratic reciprocity method. This method was developed intuitively (not actually on this modern form that you will see here) by some great number …

5. Quadratic Reciprocity 5.1. Introduction. Recall that the Legendre symbol a p is defined for an odd prime p and integer a coprime to p as a p = (1 if a is a quadratic residue (mod p); −1 …
Theorem! Nobody knows any easier way to prove Quadratic Reciprocity. This is why it’s called a ‘deep result’. I think it is said that Gauss had ten di erent proofs for the law of quadratic …

The law of quadratic reciprocity is an important result in number theory. The purpose of this thesis is to present several proofs as well as applications of the law of quadratic reciprocity.
THE LAW OF QUADRATIC RECIPROCITY NIELS KETELAARS 1. Introduction The law of quadratic reciprocity is one of the most famous and important results from number theory. …

We introduce Weil’s quadratic exponential functions, which we consider as tempered distributions. The rst two lemmas below, while straightforward, contain the germ of the reciprocity law.

Quadratic reciprocity is proved by studying the splitting behavior of primes in cyclotomic fields and their unique quadratic subfields. The Artin symbol is related to the Legendre symbol, …
