One-class genera of positive ternary quadratic forms
Published online by Cambridge University Press: 26 February 2010
Extract
We consider positive-definite ternary quadratic forms with integer coefficients. Such a form, f, can be written in matrix notation as
Here x′ is the transpose of the column vector x = {x1, x2, x3) and a,ij = aji is the coefficient of xixj in f. Clearly det A is positive and even and so
is a negative integer.
