The dataavailable to us is a Cauchy data on subboundary. We prove that with twoappropriate measurements, we can obtain a Holder stability estimate of the inverse problem.In Chapter 2, we discuss the determination of a thermal conductivity anda mobility in the linearized phase field model with measurement of only onecomponent in a small domain. Our result is the Lipschitz stability estimate of this problem.In Chapter 3, we consider the coefficient inverse problem of the structuredpopulation model. In the structured population model, an age andan individual size as well as a spatial position and time are considered asindepenent variables and then the equation has a special form. We prove a Carleman estimate for this equation and obtain a stability estimate for theinverse problem.","subitem_description_type":"Abstract"}]},"item_7_dissertation_number_26":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第27184号"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"9335","nameIdentifierScheme":"WEKO"}],"names":[{"name":"上坂, 正晃"}]}]},"item_7_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00004036","subitem_identifier_reg_type":"JaLC"}]},"item_7_select_21":{"attribute_name":"学位","attribute_value_mlt":[{"subitem_select_item":"doctoral"}]},"item_7_subject_13":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"410","subitem_subject_scheme":"NDC"}]},"item_7_text_22":{"attribute_name":"学位分野","attribute_value_mlt":[{"subitem_text_value":"Mathematical Sciences (数理科学)"}]},"item_7_text_24":{"attribute_name":"研究科・専攻","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Mathematical Sciences (数理科学研究科)"}]},"item_7_text_27":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_text_value":"博数理第365号"}]},"item_7_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院数理科学研究科"},{"subitem_text_value":"Graduate School of Mathematical Sciences, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Uesaka, Masaaki"}],"nameIdentifiers":[{"nameIdentifier":"9334","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":"2017-06-01"}],"displaytype":"detail","filename":"UesakaM_23_3_PhD_a.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"UesakaM_23_3_PhD_a.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/4045/files/UesakaM_23_3_PhD_a.pdf"},"version_id":"fe4c9e11-fdb4-42ce-894c-56da00584ff4"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-01"}],"displaytype":"detail","filename":"UesakaM_23_3_PhD_b.pdf","filesize":[{"value":"63.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"UesakaM_23_3_PhD_b.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/4045/files/UesakaM_23_3_PhD_b.pdf"},"version_id":"7f75298e-1c8c-494e-a6b2-80e10343240a"}]},"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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Coefficient inverse problems for partial differential equations in the viscoelasticity, the material science and population dynamics by Carleman estimates","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Coefficient inverse problems for partial differential equations in the viscoelasticity, the material science and population dynamics by Carleman estimates"}]},"item_type_id":"7","owner":"1","path":["391","280"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-10-23"},"publish_date":"2012-10-23","publish_status":"0","recid":"4045","relation_version_is_last":true,"title":["Coefficient inverse problems for partial differential equations in the viscoelasticity, the material science and population dynamics by Carleman estimates"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:45:44.945907+00:00"}
