报告摘要：In this talk we consider a transient branching random walk on a non-elementary hyperbolic group and show that the Hausdorff dimension of its limit set (i.e., the accumulation points on the boundary of the group) is determined by the growth rate for the two-point function of the system. As a consequence, the dimension is at most half that of the entire boundary of the group, with equality only on virtually free groups.
