This fact is confusing to our intuition. In the study of Lorentzian manifolds, Riemannian metrics are often used. But the relation be­tween the Lorentzian metrics and the Riemannian metrics are not clear in most cases. In this note we see that there are examples of Riemannian manifolds the Riemannian metrics of which are closely re­lated to the Lorentzian metrics defined on them. Specifically, we introduce a Lorentzian metric on a 3-dimensional pseudo-symmetric space (M, g) of constant type. If M is, furthermore, locally confor­mally flat, we see that the connection of the Lorentzian metric coincides with the Riemannian connec­tion of g and hence we have the relations or their curvatures.","subitem_description_type":"Other"}]},"item_3_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"1743","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ゴトウ, ミドリ"}]}]},"item_3_full_name_3":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"1744","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Goto S., Midori"}]}]},"item_3_publisher_37":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"福岡工業大学"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02876620","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10036974","subitem_source_identifier_type":"NCID"}]},"item_3_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"411","subitem_subject_scheme":"NDC"}]},"item_3_text_18":{"attribute_name":"形態","attribute_value_mlt":[{"subitem_text_value":"615984 bytes"}]},"item_3_text_38":{"attribute_name":"出版者(ヨミ)","attribute_value_mlt":[{"subitem_text_value":"フクオカ コウギョウ ダイガク"}]},"item_3_text_39":{"attribute_name":"別言語の出版者","attribute_value_mlt":[{"subitem_text_value":"Fukuoka Institute of Technology"}]},"item_3_text_48":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"紀要論文"}]},"item_3_text_49":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper"}]},"item_3_text_50":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_3_text_51":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"02"}]},"item_3_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"後藤, ミドリ"}],"nameIdentifiers":[{"nameIdentifier":"1742","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":"2020-09-14"}],"displaytype":"detail","filename":"11478-829_149p後藤ミドリ.pdf","filesize":[{"value":"616.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"11478-829_149p後藤ミドリ.pdf","url":"https://fit.repo.nii.ac.jp/record/387/files/11478-829_149p後藤ミドリ.pdf"},"version_id":"c5f65ac1-961a-445e-b0de-c878f6904641"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Lorentzian metric","subitem_subject_scheme":"Other"},{"subitem_subject":"conformally flat","subitem_subject_scheme":"Other"},{"subitem_subject":"pseudo-symmetric","subitem_subject_scheme":"Other"},{"subitem_subject":"Ricci tensor","subitem_subject_scheme":"Other"},{"subitem_subject":"Lorentzian metric","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"conformally flat","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"pseudo-symmetric","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ricci tensor","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"A NOTE ON LORENTZIAN METRICS OF 3-DIMENSIONAL CONFORMALLY FIAT MANIFOLDS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A NOTE ON LORENTZIAN METRICS OF 3-DIMENSIONAL CONFORMALLY FIAT MANIFOLDS"}]},"item_type_id":"3","owner":"6","path":["258"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-10-12"},"publish_date":"2018-10-12","publish_status":"0","recid":"387","relation_version_is_last":true,"title":["A NOTE ON LORENTZIAN METRICS OF 3-DIMENSIONAL CONFORMALLY FIAT MANIFOLDS"],"weko_creator_id":"6","weko_shared_id":-1},"updated":"2023-05-15T13:01:29.478976+00:00"}
