Abstract
Incidencestructures with an equivalence relation on the set of blocks or lines, satisfying the euclidean axiom of parallelism, are called generalised parallel structures, if on each line are at least two points and if through two different points passes at most one line. In this paper we give a coordinatization for a class of generalised parallel structures. Isomorphisms of desarguesian affine spaces induce in a well known manner regular semilinear mappings of the corresponding vector spaces. We prove an analogous theorem for generalised parallel structures and the corresponding algebraic structures.
