The Lie derivative can also be defined on differential forms.

The differential form can be derived from first principles as follows.

These, though, are usually described using the differential form of this equation given below.

They represent the differential forms of the integral equations given above.

Note the differential form of these latter strains as shown in the figure.

The description is more general in many senses and all results of differential forms can be reproduced.

The conservation laws can be written in integral or differential form.

It is often easier to work in differential form and then convert back to normal derivatives.

By saying these changes are infinitesimally small, the equation can be written in differential form.

Vectors have an action on differential forms given by the interior product.
