For this, we use the framework of sheaves over posets. We develop a notion of gluing of posets and of sheaves over posets, which we apply to construct global resolutions for equivariant sheaves. Our constructions give a natural correspondence between resolutions for reflexive equivariant sheaves and free resolutions of vector space arrangements.", "revisions": [ { "version": "v1", "updated": "2005-03-23T18:06:05.000Z" } ], "analyses": { "subjects": [ "14M25", "18F20" ], "keywords": [ "toric varieties", "construct global resolutions", "general coherent equivariant sheaves", "vector space arrangements", "free resolutions" ], "note": { "typesetting": "TeX", "pages": 48, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math......3501P" } } }
