Abstract:We prove that in various natural models of a random quotientof a group, depending on a density parameter, for each hyperbolicgroup there is some critical density under which a random quotient is stillhyperbolic with high probability, whereas above this critical value a randomquotient is very probably trivial. We give explicit characterizationsof these critical densities for the various models.
