First define a manifold with local coordinates and define a metric on .
Example 1.
Compute the inner product of two 1-forms
Example 2.
Compute the inner products of a list of monomial 2-forms.
Compute the inner product of a pair of 2-forms.
Example 3.
In this example we compute the inner products of forms defined on a Lie algebra with coefficients in a representation.
Compute the inner product of a pair of zero forms.
Compute the inner product of a pair of 1-forms.
Compute the length of a 2-form.
