Using this result, we obtain a classification for the quotient space of the space of all twistor holomorphis surfaces by conformal transformations in the special case. Moreover we show that twsitor lifts of twistor holomorphic surfaces are weakly stable as harmonic sections if ambient spaces are self-dual Einstein manifolds of non-negative scalar curvature. Conversely, if the ambient space is Euclidean space, a surface whose twistor lift is a weakly stable harmonic section is twistor holomorphic.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:20740046, 研究期間(年度):2008-2010","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「4次元リーマン多様体内の曲面のツイスターリフトを用いた研究」課題番号20740046\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-20740046/20740046seika/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学人間社会研究域学校教育系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052293","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=50349825"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=50349825","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-20740046/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-20740046/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-20740046/20740046seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-20740046/20740046seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"長谷川, 和志"}],"nameIdentifiers":[{"nameIdentifier":"2204","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"50349825","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=50349825"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-09-28"}],"displaytype":"detail","filename":"ED-PR-HASEGAWA-K-kaken 2012-4p.pdf","filesize":[{"value":"146.5 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"ED-PR-HASEGAWA-K-kaken 2012-4p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/45959/files/ED-PR-HASEGAWA-K-kaken 2012-4p.pdf"},"version_id":"427f1181-54a1-4005-9c3c-2f14092f7bf8"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"4次元リーマン多様体内の曲面のツイスターリフトを用いた研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"4次元リーマン多様体内の曲面のツイスターリフトを用いた研究"},{"subitem_title":"Research of surfaces in four-dimensional Riemannian manifolds using their twistor lifts","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2823"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-10-01"},"publish_date":"2018-10-01","publish_status":"0","recid":"45959","relation_version_is_last":true,"title":["4次元リーマン多様体内の曲面のツイスターリフトを用いた研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-01T06:04:16.387405+00:00"}
