论文摘要
我们展示了各种群体，它们在中值图（又称CAT（0）立方体复合物的一键骨骼）上进行了正确的作用，并与未接受任何适当作用的准iS-Immotem组相结合。这回答了Niblo，Sageev和Wise的问题。我们的示例都是某些立方组的准文化中心延伸。
We exhibit a variety of groups that act properly and even cocompactly on median graphs (a.k.a. one-skeletons of CAT(0) cube complexes), with quasi-isometric groups that do not admit any proper action on a median graph. This answes a question of Niblo, Sageev and Wise. Our examples are all quasi-isometrically trivial central extensions of certain cubulated groups.
