The polar vectors of all geodesics in the hyperbolic space are in the de Sitter space, and some polar vectors of geodesics in the de Sitter space can be in the hyperbolic space only when the geodesics are space-like. However, in the case of dimension 2, the polar vectors of space-like geodesics in the de Sitter space are always in the hyperbolic space.","subitem_description_type":"Abstract"}]},"item_2_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_2_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学産業理工学部 "}]},"item_2_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13495801","subitem_source_identifier_type":"ISSN"}]},"item_2_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Okada, Ikutaro"}]},"item_2_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学"}]},"item_2_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kinki University"}]},"item_2_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"岡田,  幾太郎"},{"creatorName":"オカダ, イクタロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"27317","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ローレンツ空間","subitem_subject_scheme":"Other"},{"subitem_subject":"双曲空間","subitem_subject_scheme":"Other"},{"subitem_subject":"de Sitter Space","subitem_subject_scheme":"Other"},{"subitem_subject":"測地線","subitem_subject_scheme":"Other"},{"subitem_subject":"測地線の極ベクトル","subitem_subject_scheme":"Other"},{"subitem_subject":"Lorentzian space","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hyperbolic space","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"de Sitter space","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"geodesic","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"polar vector of geodesics","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"双曲空間とde Sitter Spaceの測地線に係る関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"双曲空間とde Sitter Spaceの測地線に係る関係"},{"subitem_title":"The relation between hyperbolic space and de Sitter space with regard to their geodesics","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["3960"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-06-01"},"publish_date":"2016-06-01","publish_status":"0","recid":"15081","relation_version_is_last":true,"title":["双曲空間とde Sitter Spaceの測地線に係る関係"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T22:50:42.209442+00:00"}
