By virtue of the gap between subspaces, we derive the conditions that make the perturbation of $A_{T,S}^{(2)}$ is stable when $T,S$ and $A$ have suitable perturbations. At the same time, the explicit formulas for perturbation of $A_{T,S}^{(2)}$ and new results on perturbation bounds are obtained.", "revisions": [ { "version": "v1", "updated": "2012-07-07T08:05:42.000Z" } ], "analyses": { "subjects": [ "15A09", "47A55" ], "keywords": [ "banach spaces", "perturbation analysis", "perturbation problems", "explicit formulas", "perturbation bounds" ], "note": { "typesetting": "TeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1207.1776D" } } }
