Those properties will be discussed in connection with the characterization of flat metrics on tori by some families of geodesics and tori of revolution. The main method is the geometry of geodesics due to H. Busemann which was reconstructed in the configuration space by V. Bangert. In particular, the theory of parallels plays an important role in the present paper.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10800960","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13419951","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Innami, Nobuhiro"}],"nameIdentifiers":[{"nameIdentifier":"7409","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":"2019-07-29"}],"displaytype":"detail","filename":"5_0013.pdf","filesize":[{"value":"5.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"5_0013.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2183/files/5_0013.pdf"},"version_id":"8add169d-a699-4476-9997-1d0882d9872c"}]},"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":"Geometry of geodesics for convex billiards and circular billiards","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Geometry of geodesics for convex billiards and circular billiards"},{"subitem_title":"Geometry of geodesics for convex billiards and circular billiards","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","489"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-08"},"publish_date":"2008-04-08","publish_status":"0","recid":"2183","relation_version_is_last":true,"title":["Geometry of geodesics for convex billiards and circular billiards"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:35:00.213151+00:00"}
