An Elementary Proof of the Law of Quadratic Reciprocity over Function Fields

Let P and Q be relatively prime monic irreducible polynomials in Fq [T ] (2 q). In this paper, we give an elementary proof for the following law of quadratic reciprocity in Fq [T ]: ( Q P )( P Q ) = (−1) |P |−1 2 |Q|−1 2 , where ( Q P ) is the Legendre symbol.

A Hasse Principle for Quadratic Forms over Function Fields

We describe the classical Hasse principle for the existence of nontrivial zeros for quadratic forms over number fields, namely, local zeros over all completions at places of the number field imply nontrivial zeros over the number field itself. We then go on to explain more general questions related to the Hasse principle for nontrivial zeros of quadratic forms over function fields, with referen...

Quadratic Forms over Arbitrary Fields

Introduction. Witt [5] proved that two binary or ternary quadratic forms, over an arbitrary field (of characteristic not 2) are equivalent if and only if they have the same determinant and Hasse invariant. His proof is brief and elegant but uses a lot of the theory of simple algebras. The purpose of this note is to make this fundamental theorem more accessible by giving a short proof using only...

Quadratic Reciprocity

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 different proofs have been discovered. Here I present one proof which is not particularly well-known, due to George Rousseau [2]. (The proof was rediscovered more recently by (then) high-schooler Tim Kunisky [1].) Alt...
