We deal with smooth approximations in both space and time by employing high-order B-splines of general degree $p$. By exploiting a suitably defined perturbation of order $2p$, we devise a high-order unconditionally stable space-time isogeometric method given by a non-consistent isogeometric formulation. To illustrate the effectiveness of this stabilized isogeometric method, we perform several numerical experiments.", "revisions": [ { "version": "v2", "updated": "2023-03-17T14:28:25.000Z" } ], "analyses": { "keywords": [ "unconditionally stable space-time isogeometric method", "linear acoustic wave equation", "high-order space-time isogeometric discretizations" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
