Über niedrigdimensionale projektive Darstellungen von Kettengeometrien (Q1063228)

By means of a Grassmann mapping a chain geometry may be represented in a projective space. The dimension \(n\) of this space is rather large: In an earlier paper the author has shown that for the chain geometry corresponding to an r-dimensional algebra we have \(n=2^r-1\). In this paper he derives a represention with \(n=2r+1.\) The second part of the paper deals with a representation by means of a true modulus.
