Here, we investigate how the dynamical properties of oscillator networks are affected when some nodes are merged together to form a coarse-grained network. Moreover, we show that there exists a way of grouping nodes preserving as much as possible some crucial aspects of the network dynamics. This coarse graining approach provides a useful method to simplify complex oscillator networks, and more generally any network whose dynamics involves a Laplacian matrix.", "revisions": [ { "version": "v3", "updated": "2008-03-13T13:01:54.000Z" } ], "analyses": { "subjects": [ "05.45.Xt", "89.75.Fb" ], "keywords": [ "spectral coarse graining", "synchronization", "coarse graining techniques offer", "simplify complex oscillator networks", "laplacian matrix" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "year": 2008, "month": "May", "volume": 100, "number": 17, "pages": 174104 }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008PhRvL.100q4104G" } } }
