The use of geometric invariants has recently played an important role in the solution of classification problems in noncommutative ring theory. We construct geometric invariants of noncommutative projectivizations, a significant class of examples in noncommutative algebraic geometry. More precisely, if S is an affine, noetherian scheme, X is a separated, noetherian S-scheme, is a coherent -bimodule and is a graded ideal then we develop a compatibility theory on adjoint squares in order to construct the functor Γn of flat families of truncated -point modules of length n + 1. For n ≥ 1 we represent Γn as a closed subscheme of . The representing scheme is defined in terms of both and the bimodule Segre embedding, which we construct. When is a quantum ruled surface, we study the point modules over . More precisely, we use the geometry of the Γn 's to show that the point modules over are parameterized by the closed points of . Furthermore, when , we construct, for any -point module, a graded − -bimodule resolution. |
