diagonal quadratic form
Let’s see what a diagonal quadratic form looks like. If is diagonal whose diagonal entry in cell is , then
So the coefficients of for are all in a diagonal quadratic form. A diagonal quadratic form is completely determined by the diagonal entries of .
Remark. Every quadratic form is equivalent (http://planetmath.org/EquivalentQuadraticForms) to a diagonal quadratic form. On the other hand, a quadratic form may be to more than one diagonal quadratic form.
