ENERGY-DEPENDENT MINKOWSKI METRIC IN SPACE-TIME

The geometrical properties of the space-time endowed with a metric depending on the energy E of the considered process are obtained using the generalized Lagrange space methods. The tensor of the electromagnetic field is introduced in order to include both electromagnetic and gravitational fields in the same model. An example of energy-dependent metric is given and a comparison with other results is presented. AMS Subject Classification: 53B40, 53C60
