A graph whose graphic matroid is dual to the graphic matroid of ''G'' is known as an algebraic dual of ''G''. This, Whitney's planarity criterion can be expressed succinctly as: a graph is planar if and only if it has an algebraic dual. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Whitney's planarity criterion」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
