SummaryLet
$$\mathfrak{X}$$
denote a branching random walk in
$$\mathbb{R}^1 $$
with mean particle productionm, m>1, and with incremental spatial distributionG, withG({0}) =p andG({1})=1−p. Ifmp=1, then the minimal displacement of
$$\mathfrak{X}$$
behaves asymptotically like log logn/log 2. If the conditionG({1})=1−p is replaced byG((0, ∞))=1−p, we obtain a similar result.
