In this paper, we show that the set of mini-walls in $(0, +\\infty)$ of a fixed numerical type is locally finite. In addition, we strengthen a result of Bayer by proving that the moduli of polynomial Bridgeland semistable objects of a fixed numerical type coincides with the moduli of $(Z_m, \\mathcal P_m)$-semistable objects whenever $m$ is larger than a universal constant depending only on the numerical type. We further identify the moduli of polynomial Bridgeland semistable objects with the Gieseker/Simpson moduli spaces and the Uhlenbeck compactification spaces.", "revisions": [ { "version": "v1", "updated": "2011-03-22T19:15:30.000Z" } ], "analyses": { "subjects": [ "14J10", "14D20" ], "keywords": [ "derived category", "polynomial bridgeland semistable objects", "mini-walls", "arcara-bertram constructed bridgeland stability conditions", "fixed numerical type" ], "note": { "typesetting": "TeX", "pages": 26, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1103.4352L" } } }
