论文摘要
有限生成的组的表示空间是一个压缩，分为具有$δ$ - 薄三角形的所有空间的异构体组。理想的观点是$ \ mathbb r $ -retes上的动作。这是Culler-Morgan-Shalen理论的几何重新重新制定和扩展，该理论将表示限制到$ \ operatatorName {sl}（2，{\ Mathbb c}）$和更一般而言的$ \ propatatorNorname {o}（o}（o}（n，1）$）。本文是在90年代初编写和分发的，但从未发表过。
There is a compactification of the space of representations of a finitely generated group into the groups of isometries of all spaces with $Δ$-thin triangles. The ideal points are actions on $\mathbb R$-trees. It is a geometric reformulation and extension of the Culler-Morgan-Shalen theory concerning limits of representations into $\operatorname{SL}(2,{\mathbb C})$ and more generally $\operatorname{O}(n, 1)$. This paper was written and circulated in the early 90's, but never published.
