论文摘要
在此简短的说明中,我们表明,在几何形式上作用于猫(0)立方体配合物,实际上,与阿贝尔超平面稳定器几乎必须将其分解为免费的阿贝尔群体和表面组的免费产品。
In this short note, we show that a group acting geometrically on a CAT(0) cube complex with virtually abelian hyperplane-stabilisers must decompose virtually as a free product of free abelian groups and surface groups.
