Based on the results of math.AG/0510670, we then show that the derived categories of coherent sheaves on flag varieties of classical type are generated by complete exceptional collections. Finally, we find complete exceptional collections in the derived categories of some homogeneous spaces of the symplectic groups of small rank.", "revisions": [ { "version": "v1", "updated": "2006-12-27T22:14:37.000Z" } ], "analyses": { "subjects": [ "18E30", "14M15" ], "keywords": [ "derived categories", "coherent sheaves", "homogeneous spaces", "complete exceptional collections", "smooth base" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2006math.....12800S" } } }
