For this purpose, we construct a family of Birkhoff sections for a suspension  Anosov flow. Birkhoff sections have been constructed by using cut and paste arguments for surfaces in 3-manifolds. But we construct them directly and then we obtain piecewise linear models of the first return mappings of the Birkhoff sections. These models enable us to investigate their dilatations explicitly,  and we obtain necessary estimates.","subitem_description_type":"Abstract"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Graduate School of Mathematical Sciences, The University of Tokyo"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11021653","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13405705","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"415","subitem_subject_scheme":"NDC"}]},"item_4_text_16":{"attribute_name":"Mathematical Reviews Number","attribute_value_mlt":[{"subitem_text_value":"MR2277516"}]},"item_4_text_17":{"attribute_name":"Mathmatical Subject Classification","attribute_value_mlt":[{"subitem_text_value":"37D20(MSC2000)"},{"subitem_text_value":"37E30(MSC2000)"},{"subitem_text_value":"57N05(MSC2000)"}]},"item_4_text_33":{"attribute_name":"原稿受領日","attribute_value_mlt":[{"subitem_text_value":"2005-05-12"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Minakawa, Hiroyuki"}],"nameIdentifiers":[{"nameIdentifier":"138695","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":"2017-06-27"}],"displaytype":"detail","filename":"jms130201.pdf","filesize":[{"value":"218.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jms130201.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/40118/files/jms130201.pdf"},"version_id":"1d87fecc-b79a-4874-9e75-0c5572e67f86"}]},"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":"Examples of pseudo-Anosov homeomorphisms with small dilatations","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Examples of pseudo-Anosov homeomorphisms with small dilatations"}]},"item_type_id":"4","owner":"1","path":["6963","6964"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-03-04"},"publish_date":"2008-03-04","publish_status":"0","recid":"40118","relation_version_is_last":true,"title":["Examples of pseudo-Anosov homeomorphisms with small dilatations"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:15:08.326224+00:00"}
