Standard examples arise from holomorphic symplectic manifolds. Under mirror symmetry these autoequivalences should be mirror to Seidel's Dehn twists about lagrangian $\\mathbb P^n$ submanifolds. We give various connections to spherical objects and spherical twists, and include a simple description of Atiyah and Kodaira-Spencer classes in an appendix.", "revisions": [ { "version": "v2", "updated": "2006-02-05T23:15:26.000Z" } ], "analyses": { "subjects": [ "14J32", "18E30" ], "keywords": [ "derived categories", "autoequivalences", "standard examples arise", "seidels dehn twists", "holomorphic symplectic manifolds" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math......7040H" } } }
