若一獨立集不為其他獨立集之真子集,則稱此獨立集為最大獨立集。一個具有點集V (G) 的連通圖形G(圖形G),若存在點x ∈V (G) 使得G-x 為樹圖(林圖),則稱G 為準樹圖(準林圖)。本篇論文目的在於找到了所有不具有邊數為3 之迴圈的準樹圖(準林圖)中最大獨立集之最大數值。除此之外,我們亦描繪出達到此值之所有極圖。
A maximal independent set is an independent set that is not a proper subset of any other independent set. A connected graph (respectively, graph) G with vertex set V(G) is called a quasi -tree graph (respectively, quasi-forest graph), if there exists a vertex x ∈V ( G) such that G - x is a tree (respectively, forest) . The purpose of this paper is to determine the largest number of maximal independent sets among all quasi- tree graphs and quasi -forest graphs containing no cycle of length three, respectively. Additionally, extremal graphs achieving these values are also given.
