论文摘要
本文的第一个版本给出了另一个证明Kropholler猜想的证据，该猜想在较早的证据后，给出了档案的相对版本结束定理。山姆·谢泼德（Sam Shepherd）指出，第二个证据仍然不足。我们解释了获得正确证明的困难和可能的方法。
The first version of this paper gave another proof of the Kropholler Conjecture, which gives a relative version of Stallings Ends Theorem, following an earlier incorrect proof. It has been pointed out by Sam Shepherd that the the second proof was still inadequate. We explain the difficulty and possible ways to obtain a correct proof.
