Abstract

Suppose SS is an affine, noetherian scheme, XX is a separated, noetherian SS-scheme, E\mathcal{E} is a coherent OX{\mathcal{O}}_{X}-bimodule and IT(E)\mathcal{I} \subset T(\mathcal{E}) is a graded ideal. We study the geometry of the functor Γn\Gamma_{n} of flat families of truncated B=T(E)/I\mathcal{B}=T(\mathcal{E})/\mathcal{I}-point modules of length n+1n+1. We then use the results of our study to show that the point modules over B\mathcal{B} are parameterized by the closed points of PX2(E){\mathbb{P}}_{X^{2}}(\mathcal{E}). When X=P1X={\mathbb{P}}^{1}, we construct, for any B\mathcal{B}-point module, a graded OXB{\mathcal{O}}_{X}-\mathcal{B}-bimodule resolution.
