Ghys, É. (ed.) et al., Group theory from a geometrical viewpoint. Proceedings of a workshop, held at the International Centre for Theoretical Physics in Trieste, Italy, 26 March to 6 April 1990. Singapore: World Scientific. 64-167 (1991).
Summary: We give a survey of various properties of path-metric spaces satisfying the hyperbolicity criterion defined by Gromov. In particular we show the equivalence of various formulations of this criterion.
