How to fill out binary quadratic forms genus

How to fill out binary quadratic forms genus:

1. Understand the concept of a binary quadratic form: A binary quadratic form is a polynomial of degree two in two variables. It can be written in the form ax^2 + bxy + cy^2, where a, b, and c are coefficients.
2. Determine the genus of the binary quadratic form: The genus of a binary quadratic form refers to the set of all equivalent forms under the action of the modular group. To find the genus, you need to calculate the discriminant of the form, which is given by Δ = b^2 - 4ac. The genus depends on the congruence class of the discriminant modulo 8 and can be determined using relevant mathematical techniques.
3. Calculate the class number and class representatives: The class number of a binary quadratic form represents the number of inequivalent forms in a given genus. To calculate the class number, you need to find the class representatives, which are the minimal forms in each genus. This process usually involves reducing the forms to standard forms using appropriate integral linear transformations.
4. Apply transformation rules: To fill out the binary quadratic forms genus, you may need to apply certain transformation rules depending on the specific form and its properties. These rules involve operations such as changing signs, exchanging variables, and applying modular substitutions.
