# Ming Fang : Miscellany on branching random walks

Branching random walk can be viewed as particles performing random walks while branching at integer time. We review some of the existing results on the maximal (or minimal) displacement, when each particle moves and branches independently according the same step distribution and the same branching law. Then we will compare them with similar but different models. Roughly speaking, in one variation, we will consider the asymptotic behavior of the particle at time n, whose ancestorsÂ? location are consistently small. In another variation, we will consider the maximal displacement for the model, where the step distributions vary with respect to time.
