On quasiconvex subgroups of word hyperbolic groups

Published in Geometriae Dedicata. 2001, vol. 87, no. 1/3, p. 191 - 208
Abstract We prove that a quasiconvex subgroup H of in¢nite index of a torsion free word hyperbolic group can be embedded in a larger quasiconvex subgroup which is the free product of H and an in¢nite cyclic group. Some properties of quasiconvex subgroups ofword hyperbolic group are also discussed.
