Maxwell Equations in Potential Fields...

Maple

I wish to express the Maxwell equations in potential fields deriving from a Lagrangian in cartesian coordinates, but expressed in vectorial form; But I am receiving an message error that I do not understand.

Initial Definitions:

I wish in this work to express the Maxwell equations deriving from the Lagrangian in the fields and

 (1.1)

but expressed in vectorial form;

 (1.2)

 (1.3)

Some definitions

Defining the Maxwell tensor

 (2.1)

Defining the field A with their components:

 >
 (2.2)
 >
 (2.3)

Applying:

Term 1:

 (4.5)

What is the origin of the two error messages above? I did some wrong definition? Why this works in t and z but not in x and y?

Tensor To Vector Form...

Maple

Hello;

I wish to express a tensorial equation or expression a simplified vector form.

In the worksheet attached, I was trying to express Maxwell Equations in the familiar vector form from the tensorial form, using the tensor.

But I cannot achieve the familiar tensor form. If someone can give a hand, it would help me a lot.
