Ideal boundary of 7-systolic complexes and groups
arXiv:0711.4081
Abstract
We prove that ideal boundary of a 7-systolic group is strongly hereditarily aspherical. For some class of 7-systolic groups we show their boundaries are connected and without local cut points, thus getting some results concerning splittings of those groups.
