Abstract
The theory of Minkowski-planes has been initiated by W.Benz as an abstraction of the geometry of plane sections of a non degenerated ruled quadric in three-dimensional projective space. We give some basic definitions and concepts of this theory, including a list of properties of circle-bundles in symmetric Minkowski-planes. Finite Minkowski planes of even order are symmetric.
Minkowski-planes may be interpreted as the geometries of sharply triply sets of permutations. The most important properties of Minkowski-planes are expressed in terms of these permutation sets. In § 6 some facts on ovoidal Minkowski-planes are discussed.
