For each case considered, we prove a lower bound and provide an example which shows the order of the bound we proved is sharp. This work is closed related to work in \\cite{Luo:Rigidity} and answers some questions raised there.", "revisions": [ { "version": "v1", "updated": "2012-07-13T18:00:50.000Z" } ], "analyses": { "subjects": [ "52C25", "05C50" ], "keywords": [ "lower bound", "connectivity assumptions", "planar rigidity matrix", "generic realizations", "general position" ], "note": { "typesetting": "TeX", "pages": 15, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1207.3319L" } } }
