Independence property and hyperbolic groups
arXiv:0706.3021 · doi:10.2178/bsl/1208358845
Abstract
We prove that existentially closed -groups have the independence property. This is done by showing that there exist words having the independence property relatively to the class of torsion-free hyperbolic groups.
