A cycle of $T_n$ is called an enclosing cycle if at least one vertex lies inside the cycle. In this paper it is proved that a triangulation $T_n$ admits a straight-line embedding in the plane whose bounded faces are all acute triangles if and only if $T_n$ has no enclosing cycle of length $\\le 4$. Those $T_n$ that admit straight-line embeddings in the plane without obtuse triangles are also characterized.","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"en","subitem_1522300316516":"ACADEMIC PRESS INC ELSEVIER SCIENCE"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/568"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0095-8956"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AA00695859"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"en","subitem_1522650091861":"Journal of Combinatorial Theory Series B"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2003-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicPageEnd":"245","bibliographicPageStart":"237","bibliographicVolumeNumber":"88"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"AM","subitem_1600292170262":"http://purl.org/coar/version/c_ab4af688f83e57aa"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_1522306287251":{"subitem_1522306382014":"URI","subitem_1522306436033":"http://www.sciencedirect.com/science/journal/00958956"}},{"subitem_1522306287251":{"subitem_1522306382014":"DOI","subitem_1522306436033":"10.1016/S0095-8956(02)00044-8"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"maehara_h04.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2000877/files/maehara_h04.pdf"},"version_id":"0a2e09d2-9f3d-46e5-80d0-e16debe8231b"}]},"item_title":"Plane graphs with straight edges whose bounded faces are acute triangles","item_type_id":"15","owner":"1","path":["1642838338003","1642838405037"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-06-14"},"publish_date":"2007-06-14","publish_status":"0","recid":"2000877","relation_version_is_last":true,"title":["Plane graphs with straight edges whose bounded faces are acute triangles"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-08-03T05:36:20.932292+00:00"}
