finding unimodular substitutions
Hi,
does anyone know a method for finding a unimodular substitution from one
binary quadratic form ( \( ax^2 + bxy + cy^2 \) ) to another given that they are equivalent?
I'd like a find a unimodal substitution
\(x\prime = \alpha x + \beta y \)
\(y\prime = \gamma x + \delta y \)
with integer coefficients which transforms
\(29x^2 + 256xy + 565y^2\) into \(x^2 + y^2 \)
Can anyone help?
