A hybrid tree in a linear graph is a generalized concept of a tree and a cotree. And thus, to examine the properties of hybrid trees seems to be of considerable importance. In this paper, a set of hybrid trees in a linear graph is classified according to the number of edges in the element of it, and a hybrid tree graph is defined as a linear graph which represents the relations among the elements of the set of hybrid trees. And it is shown that a hybrid tree graph is balanced. Using this property, the relationships between the above classification of a set of hybrid trees and the structure of the hybrid tree graph are presented. These results are useful in the realization of a hybrid tree graph.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "167900", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Sengoku, Masakazu"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "北海道大学"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00230223", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0385602X", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "仙石, 正和"}], "nameIdentifiers": [{"nameIdentifier": "167899", "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": "2019-08-21"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "S65_81-86.pdf", "filesize": [{"value": "506.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 506600.0, "url": {"label": "S65_81-86.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/30244/files/S65_81-86.pdf"}, "version_id": "e816bb98-dbe4-4d6a-890a-c0b1c07b01a9"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "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": "混成木グラフとその均衡性", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "混成木グラフとその均衡性"}, {"subitem_title": "混成木グラフとその均衡性", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1290"], "permalink_uri": "http://hdl.handle.net/10191/22365", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-05-17"}, "publish_date": "2013-05-17", "publish_status": "0", "recid": "30244", "relation": {}, "relation_version_is_last": true, "title": ["混成木グラフとその均衡性"], "weko_shared_id": null}
