On the limit set of a geometrically infinite Kleinian group
  For a torsion free Kleinian group $\Gamma$ without parabolics, we consider the decomposition of the limit set $L(\Gamma)$ into conical and ending limit sets and compare the Patterson-Sullivan measure with the harmonic measure on $L(\Gamma)$ when $L(\Gamma)=S^2_\infty$.
