In December 1907, Minkowski expressed the Maxwell equations in the very beautiful and compact 4dimensional form: lor f = -s, lor F \* = 0. Here 'lor', an abbreviation of Lorentz, represents the 4dimensional differential operator. We study Minkowski's derivation and show how these equations generaliz

β¦ Synopsis
The gyroscopic invariance implies the representation of the antisymmetric part of the Hermite-symmetric metric by a vector potential. Therefore we introduce the six functions of this antisymmetric part in general as derived by two vector potentials. Then Einstein's variational principle leads to a slight modification of the Einstein-Schrodinger equations, which just encludes Minkowski's form of the energy-momentum tensor for the electromagnetic field and the gluon field.

This interpretation was proposed by TREDER (1980, 1983), who had derived this force already 1957 (TREDER 1957), then later introducing the confinement condition :

## Abstract The methods of extended thermodynamics are employed to establish a set of closure equations for the turbulent fields. The main advantage of its use resides in the elimination of all arbitrariness in the selection of the constitutive variables and basic model for the average fields prese
