本論文旨在研究 De Loera, Peterson,以及 Su 將 Sperner 引理推廣至多面體三角分割上 Sperner 標號的情形。藉由圖論術語表達路徑跟隨法,我們得知該結果的一個建構證明。
The purpose of this thesis is to study a generalized Sperner’s lemma of De Loera, Peterson, and Su for Sperner’s labellings on triangulations of polytopes. We learn a constructive proof of the result by means of path-following method which is represented by graph theory terminologies.
