We show a necessary and sufficient condition on initial values guaranteeing that values of the corresponding solutions over the whole spatial domain and t≧t$F_0$ (given time), uniquely determine coefficients in the equation. Moreover for any given initial values, we specify a spatial subdomain where all coefficients can be determined from the above-mentioned values of the solutions. Finally we prove : in the case of the one spatial dimension, such a domain is maximal among subdomains where coefficients can be uniquely determined.","subitem_description_type":"Abstract"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00040983","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The University of Tokyo"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10538733","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02897520","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"410","subitem_subject_scheme":"NDC"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Mathematics, College of Arts and Sciences, University of Tokyo|Department of Applied Mathematics, Faculty of Engineering Kobe University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yamamoto, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"139862","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakagiri, Shin-Ichi"}],"nameIdentifiers":[{"nameIdentifier":"139863","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":"2017-06-27"}],"displaytype":"detail","filename":"scp042002.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"scp042002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/40992/files/scp042002.pdf"},"version_id":"64036c7a-1926-4409-bad0-489877b50ae8"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Identification Problems for Partial Differential Equations of Hyperbolic Type","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Identification Problems for Partial Differential Equations of Hyperbolic Type"}]},"item_type_id":"4","owner":"1","path":["7291","7293"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-11-19"},"publish_date":"2008-11-19","publish_status":"0","recid":"40992","relation_version_is_last":true,"title":["Identification Problems for Partial Differential Equations of Hyperbolic Type"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:14:21.632590+00:00"}
