Genera of rationally equivalent integral binary quadratic forms
Published online by Cambridge University Press: 14 November 2011
Synopsis
A formula is given for the number of genera of primitive integral binary quadratic forms of discriminant D which lie in a rational equivalence class. In particular, necessary and sufficient conditions for the genus and rational equivalence class to coincide are given in terms of the prime factorisation of D.
