An appropriate Hilbert setting leads to an integration-by-parts formula in Sobolev spaces of negative order and eventually allows us to use semigroup theory leading to analytic well-posedness, hence sharpening regularity results previously obtained by other authors. In doing so we introduce a parametrization of such integral conditions that includes known cases but also shows the connection with more usual boundary conditions, like periodic ones. In the self-adjoint case, we even obtain eigenvalue asymptotics of so-called Weyl's type.", "revisions": [ { "version": "v4", "updated": "2014-01-03T21:37:16.000Z" } ], "analyses": { "subjects": [ "47D06", "35J20", "34B10" ], "keywords": [ "wave equations", "spectral properties", "non-local conditions", "usual boundary conditions", "integral constraints" ], "note": { "typesetting": "TeX", "pages": 23, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1112.0415M" } } }
