Koszul Configurations of Points in Projective Spaces
نویسنده
چکیده
We prove a new criterion for the homogeneous coordinate ring of a finite set of points in Pn to be Koszul. Like the well known criterion due to Kempf [7] it involves only incidence conditions on linear spans of subsets of a given set. We also give a sufficient condition for the Koszul property to be preserved when passing to a subset of a finite set of points in Pn.

Configurations of Flats, I: Manifolds of Points in the Projective Line
The topological manifolds arising from configurations of points in the real and complex projective lines are classified. Their topology and combinatorics are described for the real case. A general setting for the study of the spaces of configurations of flats is established and a projective duality among them is proved in its full generality.
متن کاملSe p 20 01 Braids , trees , and operads
The space of unordered configurations of distinct points in the plane is aspherical, with Artin’s braid group as its fundamental group. Remarkably enough, the space of ordered configurations of distinct points on the real projective line, modulo projective equivalence, has a natural compactification (as a space of equivalence classes of trees) which is also (by a theorem of Davis, Januszkiewicz...
متن کاملKoszul Bicomplexes and Generalized Koszul Com- Plexes in Projective Dimension One
We describe Koszul type complexes associated with a linear map from any module to a free module, and vice versa with a linear map from a free module to an arbitrary module, generalizing the classical Koszul complexes. Given a short complex of finite free modules, we assemble these complexes to what we call Koszul bicomplexes. They are used in order to investigate the homology of the Koszul comp...
متن کاملNoncommutative Koszul filtrations
A standard associative graded algebra R over a field k is called Koszul if k admits a linear resolution as an R-module. A (right) R-module M is called Koszul if it admits a linear resolution too. Here we study a special class of Koszul algebras — roughly say, algebras having a lot of Koszul cyclic modules. Commutative algebras with similar properties (so-called algebras with Koszul filtrations)...
