Schubert varieties and finite free resolutions of length three

چکیده
In this paper we describe the relationship between finite free resolutions of perfect ideals in split format (for Dynkin formats) and certain intersections opposite Schubert varieties with big cell for homogeneous spaces $G/P$ where $P$ is a maximal parabolic subgroup.

Small resolutions of minuscule Schubert varieties
Let X be a minuscule Schubert variety. In this article, we use the combinatorics of quivers to define new quasi-resolutions of X . We describe in particular all relative minimal models π̂ : X̂ → X of X and prove that all the morphisms π̂ are small (in the sense of intersection cohomology). In particular, all small resolutions of X are given by the smooth relative minimal models X̂ and we describe a...
متن کاملMultiplicities on Schubert Varieties
We calculate using Macaulay 2 the multiplicities of the most singular point on Schubert varieties on Gl(n)/B for n = 5, 6. The method of computation is described and tables of the results are included.
متن کاملLarge Schubert Varieties
For a semisimple adjoint algebraic group G and a Borel subgroup B, consider the double classes BwB in G and their closures in the canonical compactification of G; we call these closures large Schubert varieties. We show that these varieties are normal and Cohen-Macaulay; we describe their Picard group and the spaces of sections of their line bundles. As an application, we construct geometricall...
متن کاملFinite Free Resolutions and 1-Skeletons of Simplicial Complexes
A technique of minimal free resolutions of Stanley–Reisner rings enables us to show the following two results: (1) The 1-skeleton of a simplicial (d − 1)-sphere is d-connected, which was first proved by Barnette; (2) The comparability graph of a non-planar distributive lattice of rank d − 1 is d-connected.
متن کاملSchubert Polynomials and Classes of Hessenberg Varieties
Regular semisimple Hessenberg varieties are a family of subvarieties of the flag variety that arise in number theory, numerical analysis, representation theory, algebraic geometry, and combinatorics. We give a “Giambelli formula” expressing the classes of regular semisimple Hessenberg varieties in terms of Chern classes. In fact, we show that the cohomology class of each regular semisimple Hess...
