Sufficient conditions for the existence of feedback solutions are stated using integrability of stochastic processes. In the case of power and logarithmic utility functions, more straightforward conditions are given and the continuity of optimal strategies is proved.","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_17":{"attribute_name":"Mathmatical Subject Classification","attribute_value_mlt":[{"subitem_text_value":"90A09(MSC1991)"},{"subitem_text_value":"60H30(MSC1991)"}]},"item_4_text_33":{"attribute_name":"原稿受領日","attribute_value_mlt":[{"subitem_text_value":"2005-04-12"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Fukaya, Ryuji"}],"nameIdentifiers":[{"nameIdentifier":"138710","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":"jms120302.pdf","filesize":[{"value":"283.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jms120302.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/40129/files/jms120302.pdf"},"version_id":"ec361858-c9f1-4419-be09-83ec7fb42453"}]},"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":"Application of Stochastic Flows to Optimal Portfolio Strategies","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Application of Stochastic Flows to Optimal Portfolio Strategies"}]},"item_type_id":"4","owner":"1","path":["6971","6972"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-03-04"},"publish_date":"2008-03-04","publish_status":"0","recid":"40129","relation_version_is_last":true,"title":["Application of Stochastic Flows to Optimal Portfolio Strategies"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:15:12.974270+00:00"}
