摘   要:

Consider a supercritical branching random walk taking values on a regular tree. We obtain simultaneously the Hausdorff dimensions of the level sets $E(\alpha, \, \beta)$ of infinite branches in the boundary of the tree (endowed with its standard metric) along which the speed of the BRW have limit points belonging to the given interval $[\alpha, \, \beta]$. Based on joint work with Shuwen Lai (NKU) and Heng Ma (PKU).
