We provide a few results regarding construction of new $J$-tight fusion frame from given $J$-tight fusion frames. We also characterize any uniformly $J$-definite subspace of a Krein space $\\mathbb{K}$ in terms of a $J$-fusion frame inequality. Finally we generalize the fundamental identity of frames in Krein space $J$-fusion frame setting.", "revisions": [ { "version": "v1", "updated": "2016-12-01T20:49:35.000Z" } ], "analyses": { "subjects": [ "42C15", "46C05", "46C20" ], "keywords": [ "krein space", "j-fusion frames", "tight fusion frame", "properties", "fusion frame inequality" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
