This means that these theories can be ultraviolet complete quantum theories of gravity. As physical applications of higher derivative gravities, we have constructed charged black hole solutions in 4 to 10 dimensions as well as de Sitter cosmological solutions even for negative cosmological constant. The latter is viable solution for early cosmology. We have also shown the consistency of massive gravity under arbitrary backgrounds. These results give step towards verification of quantum gravity in this approach.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C);  研究期間：2012～2015;   課題番号：24540290;   研究分野：素粒子論;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-24540290/"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"OHTA, Nobuyoshi"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"太田, 信義"},{"creatorName":"オオタ, ノブヨシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-17"}],"displaytype":"detail","filename":"24540290seika.pdf","filesize":[{"value":"96.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"24540290seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/18041/files/24540290seika.pdf"},"version_id":"8bc5527b-8570-4e98-a44c-d581a99c7c9f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"量子重力理論","subitem_subject_scheme":"Other"},{"subitem_subject":"高階微分","subitem_subject_scheme":"Other"},{"subitem_subject":"厳密くりこみ群","subitem_subject_scheme":"Other"},{"subitem_subject":"漸近安全性","subitem_subject_scheme":"Other"},{"subitem_subject":"紫外固定点","subitem_subject_scheme":"Other"},{"subitem_subject":"超弦理論","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"高階微分を含む一般化重力理論と超弦理論の検証","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"高階微分を含む一般化重力理論と超弦理論の検証"},{"subitem_title":"Generalized Gravity with Higher Order Derivatives, Superstring Theories and their Verification","subitem_title_language":"en"}]},"item_type_id":"8","owner":"29","path":["4296"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-10-17"},"publish_date":"2016-10-17","publish_status":"0","recid":"18041","relation_version_is_last":true,"title":["高階微分を含む一般化重力理論と超弦理論の検証"],"weko_creator_id":"29","weko_shared_id":-1},"updated":"2023-06-20T22:10:27.371629+00:00"}
