We classify all possible JSJ decompositions of doubles of free groups of rank two, and we also compute the Makanin–Razborov diagram of a particular double of a free group and deduce that in general limit groups are not freely subgroup separable.

双自由组的JSJ分解

我们将所有可能的 JSJ 分解对二阶自由群的双精度进行分类,并且我们还计算了自由群的特定双精度的 Makanin-Razborov 图,并推断一般极限群不是自由子群可分的。
