论文摘要
我们给出了一种算法,该算法计算固定子组和稳定图像,以适用于自由组的任何内态二$ f_2 $的内态性,以$ f_2 $的答案,这是损失在1984年提出的问题和文图拉问题。
We give an algorithm which computes the fixed subgroup and the stable image for any endomorphism of the free group of rank two $F_2$, answering for $F_2$ a question posed by Stallings in 1984 and a question of Ventura.
