But, in the case of an abstract abelian variety, many problems are still left open. In the present paper we shall study some properties of non-degenerate divisors. First the theorem of Riemann-Roch will be stated as follows : Let X be a positive non-degenerate divisor on an abelian variety A of dimension n. Then the dimension l(X) of the complete linear system |X| is equal to (X^<(n)>)/n! and also equal to (-1)^<n+1>x_A(X), where (X^<(n)>) means the n-fold intersection number of X and x_A(X) means the virtual arithmetic genus of X. In the next place let A and B be isogenous abelian varieties and let λ be a homomorphism from A onto B. If Y is a divisor on B, then two matrices E_l(λ^<-1>(Y)) and E_l(Y) are combined by the relation E_l(λ^-(Y))=^tM_l(λ)ヅ_l(Y)ネ_l(λ), where l is a prime number different from the characteristic of our geometry. This suggests to us that, if Y is positive non-degenerate, then l(λ^<-1>(Y)) is equal to v(λ)レ(Y). Actually a proof was given under\\\n an additional assumption in a recent paper [4] by Morikawa. In §2 we shall show that this additional assumption can be omitted. The above equality plays an important role in the algebraic treatment of the theorem of Frobenius, and we shall discuss it in a forthcoming paper. Lastly the existence theorem of a basic polar divisor (in the sense of numerical equivalence) on a polarized abelian variety will be proved. I wish to express here my hearty thanks to Professors S. Koizumi and T. Matsusaka for their kind advices.","subitem_description_type":"Other"}]},"item_11_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"69453","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ニシ, ミエオ"}]}]},"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":"802127 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"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nishi, Mieo"}],"nameIdentifiers":[{"nameIdentifier":"69452","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西, 三重雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"69454","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":"KJ00004829470.pdf","filesize":[{"value":"802.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004829470.pdf","url":"https://teapot.lib.ocha.ac.jp/record/35023/files/KJ00004829470.pdf"},"version_id":"d2b6e93d-08ab-42f5-8422-3a88071a4eb4"}]},"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":"Some Results on Abelian Varieties","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Some Results on Abelian Varieties"}]},"item_type_id":"11","owner":"1","path":["590"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-30"},"publish_date":"2008-04-30","publish_status":"0","recid":"35023","relation_version_is_last":true,"title":["Some Results on Abelian Varieties"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-12T05:39:56.719266+00:00"}
