Tachibana and Y. Ogawa [1]. THEOREM 1.^2) Let M be a compact (2m+1)-dimensional Sasakian space. If any sectional curvature of M is larger than 1/2m, the second Betti number vanishes ; i.e. b_2(M)=0. In this paper, by making use of Berger's method [2] we shall get a little better result, namely, THEOREM 2. Let M be a compact (2m+1)-dimensional Sasakian space. If any sectional curvature of M is larger than (4m-3)/4m(2m-1), then b_2(M)=0. The authors wish to express their sincere gratitude to Professor S. Tachibana who offered them many suggestions.","subitem_description_type":"Other"}]},"item_11_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"69728","nameIdentifierScheme":"WEKO"}],"names":[{"name":"オガワ, ヨウスケ"}]},{"nameIdentifiers":[{"nameIdentifier":"69729","nameIdentifierScheme":"WEKO"}],"names":[{"name":"タニ, マリコ"}]}]},"item_11_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"お茶の水女子大学"}]},"item_11_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00033958","subitem_source_identifier_type":"NCID"}]},"item_11_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00298190","subitem_source_identifier_type":"ISSN"}]},"item_11_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"400","subitem_subject_scheme":"NDC"}]},"item_11_text_18":{"attribute_name":"形態","attribute_value_mlt":[{"subitem_text_value":"276227 bytes"}]},"item_11_text_47":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"紀要論文"}]},"item_11_text_48":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper"}]},"item_11_text_49":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_11_text_50":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"03"}]},"item_11_text_79":{"attribute_name":"所属","attribute_value_mlt":[{"subitem_text_value":"Department of Mathematics, Faculty of Science, Ochanomizu University"},{"subitem_text_value":"Department of Mathematics, Faculty of Science, Ochanomizu University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ogawa, Yosuke"}],"nameIdentifiers":[{"nameIdentifier":"69726","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tani, Mariko"}],"nameIdentifiers":[{"nameIdentifier":"69727","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小川, 洋輔","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"69730","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"谷, 真理子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"69731","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":"2018-04-19"}],"displaytype":"detail","filename":"KJ00004829643.pdf","filesize":[{"value":"276.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004829643.pdf","url":"https://teapot.lib.ocha.ac.jp/record/34956/files/KJ00004829643.pdf"},"version_id":"49dd8fea-c490-48ec-b1d2-8624e40d9a50"}]},"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":"On a (2m+1)-dimensional Sasakian Space with Sectional Curvature>(4m-3)/4m(2m-1)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"On a (2m+1)-dimensional Sasakian Space with Sectional Curvature>(4m-3)/4m(2m-1)"}]},"item_type_id":"11","owner":"1","path":["608"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-30"},"publish_date":"2008-04-30","publish_status":"0","recid":"34956","relation_version_is_last":true,"title":["On a (2m+1)-dimensional Sasakian Space with Sectional Curvature>(4m-3)/4m(2m-1)"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-12T05:39:46.319901+00:00"}
