After measuring the surface area distribution (SAD) which is the three-dimensional analog of the loop length distribution (LLD) in two-dimensional quantum gravity, we classify the fractal structures into three types: (i) In the strong coupling (hot) phase, strong gravity makes the space-time one crumpled mother universe with many fluctuating baby universes of small size around it. This is a crumpled phase with a large Hausdorff dimension dH=4.98±0.05. The topologies of the sections are extremely complicated. (ii) At the critical point, we observe that the space-time is a pseudo-fractal manifold which has one mother universe with many baby universes of small and middle size around it. The Hausdorff dimension dH is 3.93±0.05. We observe some scaling behaviors for the sections of the manifold. This manifold resembles the fractal surface observed in two-dimensional quantum gravity. (iii) In the weak coupling (cold) phase, the mother universe disappears completely and the space-time seems to be a branched-polymer with a small Hausdorff dimension dH=1.948±0.003. almost all of the sections have the spherical topology S2 in the weak coupling phase.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier "}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/S0370-2693(97)01320-8"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/S0370-2693(97)01320-8","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 1998 Elsevier Science B.V."}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03702693 ","subitem_source_identifier_type":"ISSN"}]},"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":"HAGURA, Hiroyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TSUDA, Noritsugu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YUKAWA, Tetsuyuki"}],"nameIdentifiers":[{}]}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Phases and fractal structures of three-dimensional simplicial gravity","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Phases and fractal structures of three-dimensional simplicial gravity"},{"subitem_title":"Phases and fractal structures of three-dimensional simplicial gravity","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"21","path":["124","284"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-01-25"},"publish_date":"2013-01-25","publish_status":"0","recid":"3346","relation_version_is_last":true,"title":["Phases and fractal structures of three-dimensional simplicial gravity"],"weko_creator_id":"21","weko_shared_id":21},"updated":"2023-06-20T14:33:06.307795+00:00"}
