On a possible new type of a T odd skewon field linked to electromagnetism
Friedrich W. Hehl, Yuri N. Obukhov, Guillermo F. Rubilar
In the framework of generally covariant (pre-metric) electrodynamics (``charge & flux electrodynamics''), the Maxwell equations can be formulated in terms of the electromagnetic ex…

Spacetime metric from linear electrodynamics II
Friedrich W. Hehl, Yuri N. Obukhov, Guillermo F. Rubilar
Following Kottler, É.Cartan, and van Dantzig, we formulate the Maxwell equations in a metric independent form in terms of the field strength and the excitation $H=({\cal…

Classical Electrodynamics: A Tutorial on its Foundations
Friedrich W. Hehl, Yuri N. Obukhov, Guillermo F. Rubilar
We will display the fundamental structure of classical electrodynamics. Starting from the axioms of (1) electric charge conservation, (2) the existence of a Lorentz force density,…
