Introduction It is a natural question to ask whether binary definite quadratic forms over the polynomial ring F q[t] are determined, up to equivalence, by the set of polynomials they represent. Here F q is the finite field of order q and q is odd.
Webof binary quadratic forms can be viewed as groups, at a time before group theory formally existed. Beyond that, he even de ned and calculated genus groups, which are essentially quotient groups, that explain which congruence classes of numbers can be represented by given sets of forms.

WebDec 6, 2012 · The first coherent exposition of the theory of binary quadratic forms was given by Gauss in the Disqnisitiones Arithmeticae. During the nine teenth century, as the theory of ideals and the rudiments of algebraic number theory were developed, it became clear that this theory of bi nary quadratic forms, so elementary and computationally … Webforms is essentially the same as studying the class groups of quadratic elds. Here, we focus on the forms, as this allows us to derive a version of the class number formula in the scope of this talk. In the rst part of the talk, we will derive some facts about the binary quadratic forms. In the second part, we prove the class number formula ...
