Minkowski timespace

To begin with, here, we shall present the basic principles and the expressions of the classic quantities, such as the proper time and the universal velocity in the Minkowski timespace. The law of d3mamics of the material point is then stated. 

In this chapter, we shall first introduce the various quantities characterizing an electric medium with m dtiple components. These components are neutral or ionized chemical species and free electrons. Then, we shall recap on what is meant by a balance equation in three-dimensional space and in the Minkowski timespace. 

The interface gradient operator, which we have previously used in three-dimensional space, is generahzed to apply to the Minkowski timespace. The general form of the interfacial balance is then established, using the s xrface operator 4Vs. 

Part One, entitled Introduction, is made up of four chapters. Chapter 1 gives an introduction to the equations of electromagnetism in the Minkowski timespace. This mode of presentation is extended to the balance equations, first in non-polarized homogeneous mixtures in Chapter 2, and then in a polarized homogeneous fluid medium in Chapter 3.
