Systolic groups acting on complexes with no flats are word-hyperbolic

Piotr Przytycki (2007)

Similarity:

We prove that if a group acts properly and cocompactly on a systolic complex, in whose 1-skeleton there is no isometrically embedded copy of the 1-skeleton of an equilaterally triangulated Euclidean plane, then the group is word-hyperbolic. This was conjectured by D. T. Wise.
