Length functions, curvature, and the dimension of discrete groups
We work with the class of groups that act properly by semisimple isometrics on complete CAT(0) spaces. Define dimss Γ to be the minimal dimension in which Γ admits such an action. By examining the nature of translation length functions we show that there exist finitely-presented, torsion-free groups...
