The trace also plays a central role in the distribution of quadratic forms.

A given quadratic form may support several different types of spinors.

They are also called -quadratic forms, particularly in the context of surgery theory.

An indefinite quadratic form is one that takes on both positive and negative values.

Let A be the matrix of the quadratic form q in a given basis.

The energy density is written if in quadratic form.

He also investigated, and wrote a book on, the theory of quadratic forms.

Remark: If we choose the field of complex numbers, there is no suitable quadratic form at all.

This example is called the hyperbolic plane in the theory of quadratic forms.

These are frequently studied in relation to the theory of quadratic forms.
