A method is given for showing that an embeddable pointαline geometry possesses an absolutely universal projective embedding. This method is applied to show that virtually every embeddable Lie incidence geometry possesses an absolutely universal embedding.
Suppose S is an affine, noetherian scheme, X is a separated, noetherian S-scheme, is a coherent X -bimodule, and β T is a graded ideal. We study the geometry of the functor n of flat families of truncated = T / -point modules of length n + 1. We then use the results of our study to show that if Proj
Some considerations suggest the conjecture that a finite Cn-geometry F with thick lines and following property (LL) is a polar space: (LL) any two points are incident with at most one line. In this paper we prove that a such geometry F is either a polar space or 'flat' extending a result of [4] to
