Fig. 4

The illustration introduces the inverse behavior of Schlingel coordinates. The orientation of the information along the spatial axes in \(\{ p_{1} \rightarrow -\infty \}\) or \(\{p_{1} \rightarrow \infty \}\) changes the position of planes in the diagram. In (a), the Schlingel coordinates follow a positive course. The coordinates in (b) are located between \(- \infty\) and \(\infty\). In (c), the temporal coordinate can only assume positive values.
