The concept of characteristics can not be directly applied to difference approximations for conservation laws, but it is possible to discuss difference approximations from the viewpoint of the discrete propagation of infinitesimal perturbations. In this report, we propose a new concept, ′the consistency with characteristics′, for difference approximations for scalar conservation laws and give a sufficient condition under which the consistency with characteristics is satisfied. We also disucuss deffefence approximations of conservation form horo shalar consevation laws from the viewpoint of the consistency with characteristics. Furthermore, we consider a straightforward extension of the concept to difference approximations for systems of conservation laws.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR1098000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-1098T","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所数理解析部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Computational Sciences Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"相曽, 秀昭"}],"nameIdentifiers":[{"nameIdentifier":"474331","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"AISO, Hideaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"474332","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-29"}],"displaytype":"detail","filename":"naltr1098t.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr1098t.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45357/files/naltr1098t.pdf"},"version_id":"b7619488-732a-42c9-9902-3e375b240750"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"partial differential equation;  conservation law;  difference scheme;  TVD;  consistency with characteristics","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"Difference Approximations for Hyperbolic Conservation Laws and Consistency with Characteristics","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Difference Approximations for Hyperbolic Conservation Laws and Consistency with Characteristics","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"45357","relation_version_is_last":true,"title":["Difference Approximations for Hyperbolic Conservation Laws and Consistency with Characteristics"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:40:50.563319+00:00"}
