Abstract

We consider a branching random walk $$S_nX(t)$$ S n X ( t ) on a supercritical random Galton–Watson tree. We compute the Hausdorff and packing dimensions of the level set $$E(\alpha )$$ E ( α ) of infinite branches in the boundary of tree endowed with random metric along which the average of $$S_n X(t)/n$$ S n X ( t ) / n have a given limit point.
