Assuming the existence of an upper solution ＄￥varphi＄ and a lower solution ＄￥psi＄ satisfying ＄￥psi￥leq￥varphi＄ , we show that the problem has extrenal periodic solutions in the order interval ＄K=[￥psi)￥varphi]＄ . Our proof is based on a general surjectivity result for the sum of two operators of monotone type and on truncation and penalization techniques. In addition we use a result of independent interest which we prove here and which says that the pseudomonotonicity property of ＄A(t, ￥cdot)＄ can be lifted to its Nemitsky operator. Finally when we impose stronger conditions on the data, we show that the extrenal solutions can be obtained with a monotone iterative process.","subitem_description_type":"Abstract"}]},"item_6_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Yokohama City University and Yokohama National University"}]},"item_6_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA0089285X","subitem_source_identifier_type":"NCID"}]},"item_6_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00440523","subitem_source_identifier_type":"ISSN"}]},"item_6_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"University of the Aegean, Department of Mathematics, Karlovassi 83200, Samos, GREECE"},{"subitem_text_value":"National Technical University, Department of Mathematics, Zografou Campus, Athens 15780, GREECE"}]},"item_6_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Avgerinos, Evgenios P."}],"nameIdentifiers":[{"nameIdentifier":"29847","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Papageorgiou, N.
